| Improve this Doc View SourceRegisterAutoFactory(IRootTargetContainer, Type)
Registers an AutoFactoryTarget for the given delegateType
, enabling
the container to automatically build and inject a delegate which uses the container to produce a result.
This method and its overload can be used for any delegate type.
Declaration
public static void RegisterAutoFactory(this IRootTargetContainer targets, Type delegateType)
Parameters
| Type | Name | Description |
|---|---|---|
| IRootTargetContainer | targets | Required. The target container in which the registration is to be made. |
| Type | delegateType | Required. Must have a non-void return type and all its parameters must be of distinct types. |
RegisterAutoFactory<TDelegate>(IRootTargetContainer)
Registers an AutoFactoryTarget for the given delegate type TDelegate
, enabling
the container to automatically build and inject a delegate which uses the container to produce a result.
This method and its overload can be used for any delegate type.
Declaration
public static void RegisterAutoFactory<TDelegate>(this IRootTargetContainer targets)
where TDelegate : Delegate
Parameters
| Type | Name | Description |
|---|---|---|
| IRootTargetContainer | targets | Required. The target container in which the registration is to be made. |
Type Parameters
| Name | Description |
|---|---|
| TDelegate | The type of delegate to be injected. Must have a non-void return type and all its parameters must be of distinct types. |
RegisterAutoFunc<TResult>(IRootTargetContainer)
Enables the automatic injection of a Func<TResult> for the given TResult
Declaration
public static void RegisterAutoFunc<TResult>(this IRootTargetContainer targets)
Parameters
| Type | Name | Description |
|---|---|---|
| IRootTargetContainer | targets | Required. The IRootTargetContainer into which the newly created target will be registered |
Type Parameters
| Name | Description |
|---|---|
| TResult | The return type of the delegate - equivalent to the service type that is to be resolved from the container when the delegate is called. |
Remarks
Note that scoping is honoured for the delegate call; with an injected auto-factory being bound to the scope from which it is resolved.

In high school I only dabbled lightly in drugs. A couple relatively moderate mushroom experiences, and one roll on ecstasy. Mainly I stuck to drinking beer and smoking pot. This all changed when I went away to school for the first time. Let me describe myself at the time I was going to college. I was fairly sociable while under the influence of alcohol, but otherwise reserved and timid. I was painfully shy at times, partially because of a childhood of rejection. I was often made to feel like an outcast because I was different, I was in the 'gifted' class at school and basically a nerd. Before I got to high school I had experimented briefly with marijuana and alcohol, as well as one experience with methamphetamine. During my high school days I stuck to drinking mainly, and didn't truly become a pothead until I became best friends with another guy, who we'll call C.B.
So I went away to college and developed a pretty good network of friends and drinking buddies. I did mushrooms a couple more times, and became a pretty big e-head over the course of my first semester. I got to the point where I would roll every one to two weeks, but then get the 'terrible tuesdays.' During this time I became more socially outward, but inside I felt hollow, like I was missing something. Partially it could be that I was in Boston while my girlfriend was still on Long Island, but it was more than that. I felt that somehow there had to be something different... the feeling is very hard to describe in words but I think many people know what I mean.
One night the mushrooms we were waiting for came through late, and expensive. I wasn't about to pay $45 for an eighth, even if they were the goods. The girl offered me a hit of acid for $5 and I agreed with some trepidation. I had heard a lot of bad stuff about acid, but I figured I'd keep it around and think about it.
After much research on the web, in the library of my college, and through online psychological journal databases (I am a psychology major working toward a degree in clinical psychology and psychoanalytic training) I decided to drop the small, white piece of paper on my way to a party with my roommate. Suffice to say, the trip changed my life.
I don't remember everything that happened, but the peak experience was something so remarkable I have yet to experience it since (and I have become something of a psychedelic devotee in the meantime). I asked my roommate to bring me home when I started feeling very strange at the party. I looked at his face and realized I could see through his pores down to the cellular level. Outside in the streets of Beacon Hill, Boston I was pelted by rain that was confusing as I tried to count each individual drop as it hit my skin and melted into me. I became liquid seconds before my mind erupted from my body, floating far above me. I was lost in some black place that was all energy and buzzing, in my mind's eye I could manipulate my visual field kind of like the smear effect on Adobe Photoshop.
At first I was frightened, but as my roommate led my blind body up the hill he later told me I said, 'I was scared, but I see it now. I see it! This is amazing!' I remember becoming conscious of the wave like pattern of reality, feeling the 'rolling of the world' in orbit around our sun. I became a snake, an animal I had previously had a phobia-like fear of (stemming from an incident with a snake getting into our house when I was a toddler in Texas, I now believe).
The trip was intense and amazing, I finally made it back to my dorm and met up with some experienced trippers who as luck would have it were also tripping on acid. The effects lasted about 16 hours from only one small tab, I suspect now that it was 'home made' because it had no graphics or logo of any sort. I don't know how much was on it, but I've taken substantial quantities of LSD since and not matched the intensity of the peak dissolution experience.
Afterwards I had a couple very dramatically visual trips, but then I found them settling into a more mental, contemplative, serene setting. The extreme release of tensions characterized by hysterical laughter and visualization effects was no longer present, instead I felt... well, good. Like I had found that warm center I knew was missing.
Since that time I have embarked on a spiritual journey that has led me to philosophy, spirituality, to understand and embrace my own Christian faith, further psychedelic experimentation, meditation, and a profound sense of doing something vitally important that I had previously not had. I became interested in the transpersonal/depth psychology of Jung, Rank, Maslowe, and Grof. Now I am on the path to becoming a certified psychoanalyst, and I attribute many of these changes to this life altering event.
My personality has become more serene. I used to be a more tense person, very pained and troubled. I can look back now at the me from high school and see him as almost a different person, certainly a previous chapter in the book of my life.
For a time following this transformative event I became overly enthusiastic about the drug and took it a LOT. Since I have calmed my usage of LSD and all other drugs down to a respectable amount. My life has settled into a domestic routine that brings me stability and happiness, though is somewhat unusual for a formerly wild, rowdy college guy. But, I like my life, and I like the glimpse of the divine that LSD granted me. It was not a miracle cure for my problems, but it was the catalyst to a process of self transformation that continues today. Thanks, Dr. Hoffman.

for(let result = iterator.next(); !result.done; result =iterator.next()) {
console.log(result.value) // result.value == 99
}
When you want to iterate though a “partially used” iterator:
let list = [1,2,3,4,5];
let iter = list[Symbol.iterator]();
let head = iter.next().value;
head == 1
let tail = [...iter];
tail == [2,3,4,5]
Implementing Iterable Objects
we will implement the Range class one more time, making it iterable without relying on a generator.
In order to make a class iterable, you must implement a
method whose name is the Symbol
Symbol.iterator
class Range {
constructor (from, to) {
this.from = from;
this.to = to;
}
has(x) { return typeof x === "number" && this.from <= x && x <= this.to; }
toString() { return `{ x | ${this.from} ≤ x ≤ ${this.to}}`; }
[Symbol.iterator]() {
let next = Math.ceil(this.from);
let last = this.to;
return {
next() {
return (next <= last) ? { value: next++ } : { done: true };
},
[Symbol.iterator]() { return this; }
};
}
}
for(let x of new Range(1,10)) console.log(x);
Logs numbers 1 to 10
[...new Range(-2,2)]
[-2, -1, 0,1, 2]
In addition to making your classes iterable, it can be quite useful to define functions that return iterable values.
Return an iterable object that iterates the result of
applying
f()
to each value from the source iterable
function map(iterable, f) {
let iterator = iterable[Symbol.iterator]();
return {
[Symbol.iterator]() { return this; },
next() {
let v = iterator.next();
if (v.done) {
return v;
}
else {
return { value: f(v.value) };
}
}
};
}
[...map(new Range(1,4), x => x*x)]
[1, 4, 9, 16]
Return an iterable object that filters the specified iterable, iterating only those elements for which the predicate returns true
function filter(iterable, predicate) {
let iterator = iterable[Symbol.iterator]();
return {
[Symbol.iterator]() { return this; },
next() {
for(;;) {
let v = iterator.next();
if (v.done || predicate(v.value)) {
return v;
}
}
}
};
}
[...filter(new Range(1,10), x => x % 2 ===
0)]
[2,4,6,8,10]
Generators
Particularly useful when the values to be iterated are not the elements of a data structure, but the result of a computation.
To create a generator, you must first define a generator
function — defined with the keyword
function*
rather than
function
When you invoke a generator function, it does not actually execute the function body, but instead returns a generator object. This generator object is an iterator.
Calling its
next()
method causes the body of the generator function to run
from the start (or whatever its current position is)
until it reaches a
yield
statement.
The value of the
yield
statement becomes the value returned by the
next()
call on the iterator.
function* oneDigitPrimes() {
yield 2;
yield 3;
yield 5;
yield 7;
}
let primes = oneDigitPrimes();
we get a generator
primes.next().value
2
primes.next().value
3
primes.next().value
5
primes.next().value
7
primes.next().done
true
Generators have a
Symbol.iterator
method to make them iterable
primes[Symbol.iterator]()
[...oneDigitPrimes()]
[2,3,5,7]
let sum = 0;
for(let prime of oneDigitPrimes()) sum += prime;
sum
17
Like regular functions, however, we can also define generators in expression form.
const seq = function*(from,to) {
for(let i = from; i <= to; i++) yield i;
};
[...seq(3,5)]
[3, 4, 5]
In classes and object literals, we can use shorthand notation to omit the function keyword entirely when we define methods.
let o = {
x: 1, y: 2, z: 3,
*g() {
for(let key of Object.keys(this)) {
yield key;
}
}
};
[...o.g()]
[“x”, “y”, “z”, “g”]
Generators often make it particularly easy to define iterable classes.
*[Symbol.iterator]() {
for(let x = Math.ceil(this.from); x <= this.to; x++)
yield x;
}
Generator Examples
Generators are more interesting if they actually generate the values they yield by doing some kind of computation.
generator function that yields Fibonacci numbers
function* fibonacciSequence() {
let x = 0, y = 1;
for(;;) {
yield y;
[x, y] = [y, x+y];
}
}
If this generator is used with the … spread operator, it will loop until memory is exhausted and the program crashes.
Use it in a
for/of
loop, however
function fibonacci(n) {
for(let f of fibonacciSequence()) {
if (n-- <= 0) return f;
}
}
fibonacci(20)
10946
This kind of infinite generator becomes more useful with
a
take()
generator like this
function* take(n, iterable) {
let it = iterable[Symbol.iterator]();
while(n-- > 0) {
let next = it.next();
if (next.done) return;
else yield next.value;
}
}
[...take(5, fibonacciSequence())]
[1, 1, 2, 3, 5]
Asynchronous Javascript
Promises
, new in ES6, are objects that represent the
not-yet-available result of an asynchronous operation.
The keywords
async
and
await
were introduced in ES2017 and provide new syntax that
simplifies asynchronous programming by allowing you to
structure your Promise based code as if it was
synchronous.
Asynchronous iterators and the
for/await
loop were introduced in ES2018 and allow you to work
with streams of asynchronous events using simple loops
that appear synchronous.
Asynchronous Programming with Callbacks
Timers
setTimeout(checkForUpdates, 60000);
let updateIntervalId = setInterval(checkForUpdates, 60000);
function stopCheckingForUpdates() {
clearInterval(updateIntervalId);
}
Events
Event-driven JavaScript programs register callback functions for specified types of events in specified contexts, and the web browser invokes those functions whenever the specified events occur.
These callback functions are called event handlers or
event listeners, and they are registered with
addEventListener()
Ask the web browser to return an object representing the HTML <button> element that matches this CSS selector:
let okay =
document.querySelector('#confirmUpdateDialogbutton.okay');
Now register a callback function to be invoked when the user clicks on that button
okay.addEventListener('click',
applyUpdate);
Network Events
JavaScript running in the browser can fetch data from a web server with code like this:
function getCurrentVersionNumber(versionCallback) {
let request = new XMLHttpRequest();
request.open("GET", "http://www.example.com/api/version");
request.send();
request.onload = function() {
if (request.status === 200) {
let currentVersion = parseFloat(request.responseText);
versionCallback(null, currentVersion);
}
else {
versionCallback(response.statusText, null);
}
};
request.onerror = request.ontimeout = function(e) {
versionCallback(e.type, null);
};
}
Promises
Promises, a core language feature designed to simplify asynchronous programming.
A Promise is an object that represents the result of an asynchronous computation. That result may or may not be ready yet, and the Promise API is intentionally vague about this: there is no way to synchronously get the value of a Promise; you can only ask the Promise to call a callback function when the value is ready.
One real problem with callback-based asynchronous programming is that it is common to end up with callbacks inside callbacks inside callbacks, with lines of code so highly indented that it is difficult to read.
Promises allow this kind of nested callback to be re-expressed as a more linear Promise chain that tends to be easier to read and easier to reason about.
Another problem with callbacks is that they can make handling errors difficult. If an asynchronous function (or an asynchronously invoked callback) throws an exception, there is no way for that exception to propagate back to the initiator of the asynchronous operation. This is a fundamental fact about asynchronous programming: it breaks exception handling. Promises help here by standardizing a way to handle errors and providing a way for errors to propagate correctly through a chain of promises.
Note that Promises represent the future results of single asynchronous computations. They cannot be used to represent repeated asynchronous computations, however.
We can’t use Promises to replace
setInterval()
because that function invokes a callback function
repeatedly, which is something that Promises are just
not designed to do.
Using Promises
How we would use this Promise returning utility function
getJSON(url).then(jsonData => {
// callback function that will be asynchronously invoked with the parsed JSON value when it becomes available.
});
The Promise object defines a then() instance method.
Instead of passing our callback function directly to
getJSON()
, we instead pass it to the then() method. When the
HTTP response arrives, the body of that response is
parsed as JSON, and the resulting parsed value is passed
to the function that we passed to
then()
.
If you call the
then()
method of a Promise object multiple times, each of the
functions you specify will be called when the promised
computation is complete.
Unlike many event listeners, though, a Promise represents a single computation, and each function registered with then() will be invoked only once.
function displayUserProfile(profile) { ...}
getJSON("/api/user/profile").then(displayUserProfile);
HANDLING ERRORS WITH PROMISES
Asynchronous operations, particularly those that involve networking, can typically fail in a number of ways, and robust code has to be written to handle the errors that will inevitably occur.
getJSON("/api/user/profile").then(displayUserProfile,
handleProfileError);
if
getJSON()
runs normally, it passes its result to
displayUserProfile()
. If there is an error (the user is not logged in, the
server is down, the user’s internet connection dropped,
the request timed out, etc.), then
getJSON()
passes an Error object to
handleProfileError()
.
In practice, it is rare to see two functions passed to then(). There is a better and more idiomatic way of handling errors when working with Promises.
To understand it, first consider what happens if
getJSON()
completes normally but an error occurs in
displayUserProfile()
. That callback function is invoked asynchronously when
getJSON()
returns, so it is also asynchronous and cannot
meaningfully throw an exception (because there is no
code on the call stack to handle it).
getJSON("/api/user/profile").then(displayUserProfile).catch(handleProfileError);
With this code, a normal result from
getJSON()
is still passed to
displayUserProfile()
, but any error in
getJSON()
or in
displayUserProfile()
(including any exceptions thrown by
displayUserProfile
) get passed to
handleProfileError()
.
Chaining Promises
One of the most important benefits of Promises is that
they provide a natural way to express a sequence of
asynchronous operations as a linear chain of
then()
method invocations, without having to nest each
operation within the callback of the previous one.
fetch(documentURL)
.then(response => response.json())
.then(document => {return render(document); })
.then(rendered => {cacheInDatabase(rendered); })
.catch(error => handle(error));
has largely been replaced by the newer, Promise-based Fetch API. In its simplest form, this new HTTP API is just the function fetch(). That promise is fulfilled when the HTTP response begins to arrive and the HTTP status and headers are available.
fetch("/api/user/profile")
.then(response => {
if (response.ok && response.headers.get("Content-Type") === "application/json") {
// What can we do here? We don't actually have the response body yet.
}
});
But although the initial Promise is fulfilled, the body
of the response may not yet have arrived. So these
text()
and
json()
methods for accessing the body of the response
themselves return Promises.
fetch("/api/user/profile")
.then(response => {
return response.json();
})
.then(profile => {
displayUserProfile(profile);
});
There is a second
then()
in the chain, which means that the first invocation of
the
then()
method must itself return a Promise. That is not how
Promises work, however.
When we write a chain of .then()
invocations, we are not registering multiple callbacks
on a single Promise object. Instead, each invocation of
the
then()
method returns a new Promise object. That new Promise
object is not fulfilled until the function passed to
then()
is complete.
fetch(theURL) // task 1; returns promise 1
.then(callback1) // task 2; returns promise 2
.then(callback2); // task 3; returns promise 3
Resolving Promises
There is actually a fourth Promise object involved as which brings up the point of what it means for a Promise to be “resolved.”
fetch() returns a Promise object which, when fulfilled,
passes a Response object to the callback function we
register. This Response object has .text(), .json(),
and other methods to request the body of the HTTP
response in various forms. But since the body may not
yet have arrived, these methods must return Promise
objects.
“task 2” calls the .json()
method and returns its value. This is the fourth Promise
object, and it is the return value of the
callback1()
function.
Let’s consider:
function c1(response) {
let p4 = response.json();
return p4;
}
// callback 1
// returns promise 4
function c2(profile) {
displayUserProfile(profile);
}
// callback 2
let p1 = fetch("/api/user/profile");
promise 1, task 1
let p2 = p1.then(c1);
promise 2, task 2
let p3 = p2.then(c2);
promise 3, task 3
In order for Promise chains to work usefully, the output of task 2 must become the input to task 3. The input to task 3 is the body of the URL that was fetched, parsed as a JSON object. But the return value of callback c1 is not a JSON object, but Promise p4 for that JSON object.
When p1 is fulfilled, c1 is invoked, and task 2 begins. And when p2 is fulfilled, c2 is invoked, and task 3 begins.
And when p2 is fulfilled, c2 is invoked, and task 3 begins. But just because task 2 begins when c1 is invoked,it does not mean that task 2 must end when c1 returns.
Promises are about managing asynchronous tasks, and if task 2 is asynchronous, then that task will not be complete by the time the callback returns.
When you pass a callback c to the
then()
method,
then()
returns a Promise p and arranges to asynchronously
invoke c at some later time. The callback performs some
computation and returns a value v. When the callback
returns, p is resolved with the value v. When a Promise
is resolved with a value that is not itself a Promise,
it is immediately fulfilled with that value.
So if c returns a non-Promise, that return value becomes the value of p, p is fulfilled and we are done. But if the return value v is itself a Promise, then p is resolved but not yet fulfilled.
At this stage, p cannot settle until the Promise v settles. If v is fulfilled, then p will be fulfilled to the same value. If v is rejected, then p will be rejected for the same reason. This is what the “resolved” state of a Promise means
the Promise has become associated with, or “locked onto,” another Promise. We don’t know yet whether p will be fulfilled or rejected, but our callback c no longer has any control over that. p is “resolved” in the sense that its fate now depends entirely on what happens to Promise v.
Let’s bring this back to our URL-fetching example. When
c1 returns p4, p2 is resolved. But being resolved is not
the same as being fulfilled, so task 3 does not begin
yet. When the full body of the HTTP response becomes
available, then the .json()
method can parse it and use that parsed value to fulfill
p4. When p4 is fulfilled, p2 is automatically fulfilled
as well, with the same parsed JSON value. At this point,
the parsed JSON object is passed to c2, and task 3
begins.
More on Promises and Errors
With synchronous code, if you leave out error-handling
code, you’ll at least get an exception and a stack trace
that you can use to figure out what is going wrong. With
asynchronous code, unhandled exceptions will often go
unreported, and errors can occur silently, making them
much harder to debug. The good news is that the .catch()
method makes it easy to handle errors when working with
Promises.
THE CATCH AND FINALLY METHODS
The .catch()
method of a Promise is simply a shorthand way to
call .then()
with null as the first argument and an error-handling
callback as the second argument.
Normal exceptions don’t work with asynchronous code.
The .catch()
method of Promises is an alternative that does work for
asynchronous code.
fetch("/api/user/profile")
.then(response => {
if (!response.ok) {
return null;
}
let type = response.headers.get("content-type");
if (type !== "application/json") {
throw new TypeError(`Expected JSON, got ${type}`);
}
return response.json();
})
.then(profile => {
if (profile) {
displayUserProfile(profile);
}
else {
displayLoggedOutProfilePage();
}
})
.catch(e => {
if (e instanceof NetworkError) {
displayErrorMessage("Check your internet connection.");
}
else if (e instanceof TypeError) {
displayErrorMessage("Something is wrong with our server!");
}
else {
console.error(e);
}
});
p1 is the Promise returned by the
fetch()
call
p2 is the Promise returned by the first .then()
call
c1 is the callback that we pass to that .then()
call
p3 is the Promise returned by the second .then()
call
c2 is the callback we pass to that call
c3 is the callback that we pass to the .catch()
call
The first thing that could fail is the fetch() request itself. Let’s say p1 was rejected with a NetworkError object.
We didn’t pass an error-handling callback function as
the second argument to the .then()
call, so p2 rejects as well with the same NetworkError
object.
Without a handler, though, p2 is rejected, and then p3 is rejected for the same reason.
At this point, the c3 error-handling callback is called, and the NetworkError-specific code within it runs.
There are a couple of things worth noting about this
code. First, notice that the error object thrown with a
regular, synchronous throw statement ends up being
handled asynchronously with a .catch()
method invocation in a Promise chain. This should make
it clear why this shorthand method is preferred over
passing a second argument to .then()
, and also why it is so idiomatic to end Promise chains
with a .catch()
call.
it is also perfectly valid to use .catch()
elsewhere in a Promise chain. If one of the stages in
your Promise chain can fail with an error, and if the
error is some kind of recoverable error that should not
stop the rest of the chain from running, then you can
insert a .catch()
call in the chain, resulting in code that might look
like this:
startAsyncOperation()
.then(doStageTwo)
.catch(recoverFromStageTwoError)
.then(doStageThree)
.then(doStageFour)
.catch(logStageThreeAndFourErrors);
If the callback returns normally, then the .catch()
callback will be skipped, and the return value of the
previous callback will become the input to the
next .then()
callback.
Once an error has been passed to a .catch()
callback, it stops propagating down the Promise chain.
A .catch()
callback can throw a new error, but if it returns
normally, than that return value is used to resolve
and/or fulfill the associated Promise, and
the
error stops propagating.
Sometimes, in complex network environments, errors can occur more or less at random, and it can be appropriate to handle those errors by simply retrying the asynchronous request.
queryDatabase()
.catch(e => wait(500).then(queryDatabase))
.then(displayTable)
.catch(displayDatabaseError);
Promises in Parallel
Sometimes,we want to execute a number of asynchronous
operations in parallel. The function
Promise.all()
can do this.
Promise.all()
takes an array of Promise objects as its input and
returns a Promise.
The returned Promise will be rejected if any of the input Promises are rejected. Otherwise, it will be fulfilled with an array of the fulfillment values of each of the input Promises.
const urls = [ /* zero or more URLs here */ ];
promises = urls.map(url => fetch(url).then(r => r.text()));
Promise.all(promises)
.then(bodies => { /* do something with the array of strings */ })
.catch(e => console.error(e));
The Promise returned by
Promise.all()
rejects when any of the input Promises is rejected. This
happens immediately upon the first rejection and can
happen while other input Promises are still pending. In
ES2020,
Promise.allSettled()
takes an array of input
Promises and returns a
Promise, just like Promise.all() does. But
Promise.allSettled()
never rejects the returned Promise, and it does not
fulfill that Promise until all of the input Promises
have settled. The Promise resolves to an array of
objects, with one object for each input Promise. Each of
these returned objects has a status property set to
"fulfilled" or "rejected." If the
status is "fulfilled", then the object will
also have a value property that gives the fulfillment
value. And if the status is "rejected", then
the object will also have a reason property that gives
the error or rejection value of the corresponding
Promise.
Promise.allSettled([Promise.resolve(1), Promise.reject(2),3]).then(results => {
results[0] // => { status: "fulfilled", value: 1 }
results[1] // => { status: "rejected", reason: 2 }
results[2] // => { status: "fulfilled", value: 3 }
});
Occasionally, you may want to run a number of Promises
at once but may only care about the value of the first
one to fulfill. In that case, you can use
Promise.race()
instead of
Promise.all()
. It returns a Promise that is fulfilled or rejected
when the first of the Promises in the input array is
fulfilled or rejected.
Making Promises
Promises in Sequence
async and await
These new keywords dramatically simplify the use of Promises and allow us to write Promise-based, asynchronous code that looks like synchronous code that blocks while waiting for network responses or other asynchronous events.
Asynchronous code can’t return a value or throw an exception the way that regular synchronous code can. And this is why Promises are designed the way the are. The value of a fulfilled Promise is like the return value of a synchronous function. And the value of a rejected Promise is like a value thrown by a synchronous function.
async
and
await
take efficient, Promise-based code and hide the Promises
so that your asynchronous code can be as easy to read
and as easy to reason about as inefficient, blocking,
synchronous code.
Given a Promise object p, the expression await p waits until p settles. If p fulfills, then the value of await p is the fulfillment value of p. On the other hand, if p is rejected, then the await p expression throws the rejection value of p.
let response = await fetch("/api/user/profile");
let profile = await response.json();
It is critical to understand right away that the
await
keyword does not cause your program to block and
literally do nothing until the specified Promise
settles. The code remains asynchronous, and the
await
simply disguises this fact. This means that any code
that uses await is itself asynchronous.
async Functions
Because any code that uses await is asynchronous, there
is one critical rule: you can only use the await keyword
within functions that have been declared with the
async
keyword.
async function getHighScore() {
let response = await fetch("/api/user/profile");
let profile = await response.json();
return profile.highScore;
}
Declaring a function
async
means that the return value of the function will be a
Promise even if no Promise-related code appears in the
body of the function.
The
getHighScore()
function is declared
async
, so it returns a Promise. And because it returns a
Promise, we can use the
await
keyword with it:
displayHighScore(await getHighScore());
Awaiting Multiple Promises
Suppose that we’ve written our
getJSON()
function using async:
async function getJSON(url) {
let response = await fetch(url);
let body = await response.json();
return body;
}
And now suppose that we want to fetch two JSON values with this function
let value1 = await getJSON(url1);
let value2 = await getJSON(url2);
The problem with this code is that it is unnecessarily sequential: the fetch of the second URL will not begin until the first fetch is complete. If the second URL does not depend on the value obtained from the firstURL, then we should probably try to fetch the two values at the same time.
let [value1, value2] = await Promise.all([getJSON(url1), getJSON(url2)]);
The for/await Loop
Suppose you have an array of URLs:
const urls = [url1, url2, url3];
You can call fetch() on each URL to get an array of Promises:
const promises = urls.map(url => fetch(url));
We could now use
Promise.all()
to wait for all the Promises in the array to be
fulfilled. But suppose we want the results of the first
fetch as soon as they become available and don’t want to
wait for all the URLs to be fetched.
for(const promise of promises) {
response = await promise;
handle(response);
}
←>
for await (const response of promises) {
handle(response);
}
both examples will only work if they are within
functions declared async; a
for/await
loop is no different than a regular await expression in
that way

- Marginal utility
- Utility increases with more stuff but at smaller and smaller rate.
Endowments (what do I have?)
- $x$ is money
- $y$ is goods
General Equilibrium Model
Exogenous Variables
- Individual $i \epsilon I$ where each $i$ has a utility and an endowment
- Welfare $W_i(x, y) = u_i(x) + v_i (y)$
- $y$ is money
- $x$ is football tickers
- Endowment $e_i = (e_{ix}, e_{iy})$
- Welfare $W_i(x, y) = u_i(x) + v_i (y)$
Endogenous Variables
- Prices $(P_x, P_y)$
- Trades, or final consumptions $(x, y)$
Equilibrium
Budget set of agent $i$ is the linear trade-off between $x, y$ defined by:
Final consumption must equal final endowment.
General Equilibrium for 2 agents:
- $\sum_i x_i = \sum_i e_{ix}
- $\sum_i y_i = \sum_i e_{iy}
- $P_x(x^i - e_{ix}) + P_y(e_{iy} - y^i) = 0$
- $P_x(x^j - e_{jx}) + P_y(e_{jy} - y^j) = 0$
- $\frac{MarginalUtility_i(x)}{MarginalUtility_i(y)} = \frac{P_x}{P_y}$
- $\frac{MarginalUtility_j(x)}{MarginalUtility_j(y)} = \frac{P_x}{P_y}$

Implicit Login¶
The Smartcrypt SDK supports implicit login, a form of login in which managed users are logged in not by providing a username and password, but by the system user who owns the process using the SDK.
Advantages of Implicit Login¶
Several features make implicit login the recommended authentication mechanism.
For back-office applications, implicit login provides the convenience of not needing to hard code, manually enter or place the credentials into a configuration file. This improves security and makes it easier to deploy applications.
For end-user applications, companies typically want the end user to login with domain credentials when running the applications. In this case, implicit login affords the ability to skip a login prompt, enabling a seamless user experience. This is particularly desirable when modifying existing business applications to incorporate Smartcrypt data protection.
How it works¶
On Windows, Integrated Windows Authentication is used. The identity of the Active Directory Domain User who launches the process using the Smartcrypt SDK is used.
On MacOS and Linux, the Kerberos system is used to identify and authenticate the user.
Domain-joined MacOS installations are automatically configured. On Linux, the
kinit program is
used. When properly configured, Linux machines will automatically run kinit
when users perform
a password-based login.
The identity of the Active Directory Domain User who launches the process using the Smartcrypt SDK is used. Setting the KRB5_CONFIG environment variable to the path to a custom krb5.conf file allows you to configure the underlying Kerberos setup.
