await sleep(1000) function sleep(ms) { return new Promise((resolve) => { setTimeout(resolve, ms); }); } code example

Example 1: nodejs promise sleep

await new Promise(r => setTimeout(r, 2000));

Example 2: javascript version of sleep

//Javascipt is asyncronous so you can't pause/block code execution
//You can delay doing something with setTimeout
setTimeout(function(){
 	alert("Sup!"); 
}, 2000);//wait 2 seconds
