difference between settimeout and setinterval in javascript code example

Example 1: difference between setTimeout() and setInterval()

.setTimeout() //executes the code after x seconds.
.setInterval() //executes the code **every** x seconds.

Example 2: setinterval vs settimeout js

var intervalID = setInterval(alert, 1000); // Will alert every second.
// clearInterval(intervalID); // Will clear the timer.

setTimeout(alert, 1000); // Will alert once, after a second.
setInterval(function(){ 
	console.log("Oooo Yeaaa!");
}, 2000);//run this thang every 2 seconds
