functionrunTask(spec){return(spec.task==='wait')?asyncTimeout(spec.duration):asyncFetch(spec.url);} Let’s see how we’d run these tasks in parallel and in sequence. A parallel solution Kicking offour tasks in
They can represent an asynchronously executed block of code, but they can also represent an asynchronously calculated value. They are especially useful in a situation where the need to serialize asynchronous code blocks arises. Promises are a delightfully malleable construct: They can be serialized, ...
If a function is declared async it will implicitly return a Promise. Inside an async function, you can await a Promise (or a function that returns a Promise), as if the Promise value was synchronously computed. Objects that are asynchronously iterable can be used with a for/await loop. ...
window.interopFunctions = { clickElement : function (element) { element.click(); } } To call a JS function that doesn't return a value, use JSRuntimeExtensions.InvokeVoidAsync. The following code triggers a client-side click event by calling the preceding JS function with the captured...
Break(CTRL + SHIFT + B): Breaks on the next statement run. Step into(F11): Steps into the function being called, or if not at a function, to the next statement. Step over(F10): Steps over the function being called, or if not at a function, to the next statement. ...

On the client side, there is often a need to load modules asynchronously at runtime in order to avoid the need for the client to download the entire codebase every time the app is loaded. Imagine you have an app like Twitter, where users can post messages or status updates. The core ...
Let’s return to our beloved dice and see that in action. Suppose we just want to throw dice asynchronously and print out the results: vartossTable = {1:'one',2:'two',3:'three',4:'four',5:'five',6:'six'};functiontoss() {returnnewRSVP.Promise(function(fulfill, reject) {varn =...
d - Done function, it's for tests that need to be run asynchronously. You may pass additional block of tests to this function and they'll be run right after. d argument makes no sense for synchrounous tests, declare such tests without it. All arguments are optional, and by the way ...
// Decode asynchronously request.onload = function() { context.decodeAudioData(request.response, function(buffer) { dogBarkingBuffer = buffer; }, onError); } request.send(); } 音频文件数据为二进制(非文本),所以我们设置要求responseType是“arraybuffer”。
