JavaScript, Function, Promise · Jan 8, 2022

Creates a promise that resolves after a given amount of time to the provided value.

  • Use the Promise constructor to create a new promise.
  • Use setTimeout() to call the promise's resolve function with the passed value after the specified delay.
const resolveAfter = (value, delay) =>
  new Promise(resolve => {
    setTimeout(() => resolve(value, delay));
resolveAfter('Hello', 1000);
// Returns a promise that resolves to 'Hello' after 1s
