The sleep() function can be used along with the async/await to get the pause between the execution. JavaScript Wait 5 Seconds Function Depending on your preference, you can use either of the two methods to use in the loops. This will execute a function after waiting a specified period of milliseconds or seconds. Asynchronous actions in Javascript can usually call upon one of these two functions.
It executes the next line of the function immediately after the timeout is SET, not after the timeout expires, so that does not accomplish the same task that a sleep would accomplish.
The features such as promises and async/await function in JavaScript helped us to use the sleep() function in an easier way.Īwait new Promise(r => setTimeout(r, 2000)) Ĭonst sleep = ms => new Promise(r => setTimeout(r, ms)) sleep( 1000 ) console.log( ‘Oh, come on’ ) Method : With setTimeout() function. However, setTimeout does not hold up execution. You can use some approaches for simulating the sleep() function in JavaScript. before getting cleared by below timeout.Ĭonsole.log("Calling after every 1 second") ĬlearInterval(intervalID) //clear above interval after 5 secondsĬonsole.log('This code to be executed after 5 second.') While in a specific case, it might be nice to have the whole engine wait for a few seconds, in general it is bad practice. Java has Thread.sleep(2000), Python has time.sleep(2), Go has time.Sleep(2 * time.Second).//called 5 times each time after one second In a programming language like C or PHP, you’d call sleep(2) to make the program halt for 2 seconds. Sometimes you want your function to pause execution for a fixed amount of seconds or milliseconds.
To transform seconds into milliseconds you will need to multiply your seconds by 1000. To complete this task, first of all, you will need to transform seconds into milliseconds. Learn how to make your function sleep for a certain amount of time in JavaScript Another way to pause your code for 5 seconds is to use the Date object with a while statement. Luckily for us, JavaScript provides a few ways for a developer to wait X seconds before executing the next line of the code. In case anybody wants to use Javascript and needs a way to sleep without any of the functions that it looks like should be included, here ya go. The two key methods to use with JavaScript are: setTimeout ( function, milliseconds) Executes a function, after waiting a specified number of milliseconds.
