Latency and timer functions in JS

Latency

SetTimeout (Code, millisec): Used to call the function after the specified number of milliseconds [set latency]

VaR timeoutid = setTimeout (function () {alert ('pop up after five seconds ');}, 5000 );

ClearTimeout (timeoutid): Used to cancel the delay set by the setTimeout Function

 

Periodic call (timer)

SetInterval (Code, millisec): Used to call a function at a specified period (in milliseconds ).

varintervalId=setInterval(function(){var timeSection=document.getElementById('time');var myDate=new Date();var mytime=myDate.toLocaleTimeString();timeSection.innerHTML=mytime;},1000);

Clearinterval (intervalid): Clear periodic calls set by setinterval

These two functions are very useful in implementing time-related dynamic effects.
