what is the difference between setinterval and settimeout code example

Example 1: 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

Example 2: setinterval vs settimeout

setTimeout allows us to run a function once after the interval of time.
setInterval allows us to run a function repeatedly, starting after the interval of time, then repeating continuously at that interval.
