Learn how to use async functions to write asynchronous, promise-based code in a cleaner style with await expressions. See syntax, description, examples, and browser compatibility of async functions.
Une fonction asynchrone est une fonction précédée par le mot-clé async, et qui peut contenir le mot-clé await. async et await permettent un comportement asynchrone, basé sur une promesse (Promise), écrite de façon simple, et évitant de configurer explicitement les chaînes de promesse.

Async/await - JavaScriptLe mot “async” devant une fonction signifie une chose simple : une fonction renvoie toujours une promesse. Les autres valeurs sont enveloppées dans une promesse résolue automatiquement. Par exemple, cette fonction renvoie une promesse résolue avec le résultat 1 ; testons-la: async function f() { return 1; } f().then(alert); // 1.

Introducing asynchronous JavaScript - Learn web development | MDNIn this article, we'll explain what asynchronous programming is, why we need it, and briefly discuss some of the ways asynchronous functions have historically been implemented in JavaScript. Prerequisites: A reasonable understanding of JavaScript fundamentals, including functions and event handlers. Objective:
The purpose of async / await functions is to simplify the behavior of using promises synchronously and to perform some behavior on a group of Promises. Just as Promises are similar to structured callbacks, async / await is similar to combining generators and promises.
