set repeating function based on time js code example
Example: 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
