In this article, we would like to show you how to use setTimeout in JavaScript.

Quick solution:

setTimeout is a method that sets a timer that executes a function or specified piece of code after the timer expires.

Basic version of setTimeout takes in two arguments:

  • a function (or piece of code) to be executed,
  • delay - time in milliseconds the timer should wait before the function or code passed in as a first argument is executed.

You can also pass additional arguments which will be passed through to the function.

Note:

You can find more information about setTimeout and passing arguments to the method - here.

Below we create a function with setTimeout inside that calls the function three times every 1 second.

Arguments passed:

  • function: action,
  • delay: 1000 (1 second).

2. setTimeout with additional arguments example

Edit

Below we create a function that takes in two arguments which we will pass through the setTimeout as additional arguments after function and delay.
