How do you make a JavaScript program wait?

The two key methods to use with JavaScript are:

  1. setTimeout(function, milliseconds ) Executes a function, after waiting a specified number of milliseconds.
  2. setInterval(function, milliseconds ) Same as setTimeout(), but repeats the execution of the function continuously.

How do you wait until your promise is resolved?

First we're waiting for the first call to be resolved, then we start the second. I want to start both first, then I want to wait until both finished. Not a millisecond more. Once this is resolved, we can access the first call value using data[0] and the second call return value with data[1] .

What is await in JavaScript?

How do you delay a function?

What is an async function JavaScript?

An async function is a function declared with the async keyword, and the await keyword is permitted within them. The async and await keywords enable asynchronous, promise-based behavior to be written in a cleaner style, avoiding the need to explicitly configure promise chains.

How do I sleep in node JS?

(Although the need for a blocking sleep in Node like async environments is rare.) let co = require('co'); const sleep = ms => new Promise(res => setTimeout(res, ms)); co(function*() console. log('Welcome to My Console,'); yield sleep(3000); console. log('Blah blah blah blah extra-blah'); );
