Another option is to use Promise.all to wait for an array of promises to resolve and then act on those.

Promises in JavaScript allow us to wait for such operations or tasks to complete their execution, and based on whether the task is fulfilled, we can take further actions. We must create a Promise class object using the new keyword to use promises. Promise takes two arguments, resolve and reject.

The await operator is used to wait for a Promise and get its fulfillment value. It can only be used inside an async function or at the top level of a module.

La promesse prend deux arguments, résoudre et rejeter. La méthode resolve() renvoie un objet de promesse qui est résolu avec une valeur. S’il y a une erreur lors de l’exécution d’une promesse, la méthode de rejet renverra une erreur. Les promesses utilisent les mots-clés async et wait.

https://javascript.info › async-await

The keyword await makes JavaScript wait until that promise settles and returns its result. Here’s an example with a promise that resolves in 1 second: async function f() { let promise = new Promise((resolve, reject) => { setTimeout(() => resolve("done!"), 1000) }); let result = await promise; alert(result); // "done!" } f();

A Promise is an object representing the eventual completion or failure of an asynchronous operation. Since most people are consumers of already-created promises, this guide will explain consumption of returned promises before explaining how to create them.

You can use promises with async/await by declaring an async function and using the await keyword before a call to a function that returns a promise. This makes the code wait at that point until the promise is settled, meaning it is either fulfilled or rejected.

https://javascript.info › task › delay-promise

Delay with a promise. The built-in function setTimeout uses callbacks. Create a promise-based alternative. The function delay(ms) should return a promise. That promise should resolve after ms milliseconds, so that we can add .then to it, like this: function delay(ms) { // your code } delay(3000).then(() => alert('runs after 3 seconds')); solution.
