do I need to create a new function everytime I use settimeout? code example

Example 1: settimeout function

setTimeout(function(){ 
$('#overlay'). modal('hide') 
}, 5000);
//#overlay will be the ID of modal which you want to hide or show modal

Example 2: javascript set timeout

var timeToWait = 3000; // 1000 = 1 second
setTimeout(() => {
	console.log("Text printed after 3 seconds");
}, timeToWait);
