Since setTimeout() is part of the window object, it can also be written as tTimeout().

That timer indicates a specific moment when there will be a trigger for that particular action. The role of setTimeout(), an asynchronous method of the window object, is to set a timer that will execute an action.

setTimeout vs setInterval - What is the difference?.

Here is what we will cover in this quick guide:

In this article, you will learn about the setTimeout() method – what it is and how you can use it in your programs. Something like that is possible with JavaScript. You may need certain lines of code to execute at a point in the future, when you explicitly specify, rather than all the code executing synchronously. The implementation of such a sleep function, involves 'Promisifying' the setTimeout function, and then using the Async/Await syntax to provide a synchronous feel to a rather asynchronous function.Sometimes you might want to delay the execution of your code. For a quick recap of the syntax involved, see Callback, Promise and Async/Await by Example in JavaScript. We can implement such a sleep function by combining the capabilities of Promises and Async/Await in JavaScript. But this is not to say we can't implement one! Unfortunately, this does not exist natively in JavaScript. console.log('Executing code.') Ī more convenient option would be to have something similar to: console.log('Executing code.') This is due to the fact that setTimeout is an asynchronous function, hence one would have to continue the execution of the code, in the callback passed to it, after the elapsed time. The only problem is, using setTimeout is not as convenient as one would like. JavaScript does not have a similar sleep function, although it has the setTimeout function which can be used to achieve a similar purpose. Not surprising this functionality is often implemented via a function usually named sleep. Most popular mainstream languages have a sleep functionality that allows for the pausing of code execution for a specified amount of time.
