whack your browser – memory leak. Being a web developer, the IE is something we like or hate. ie is wide-used but crabby in some way. For example, memory leak is serious issue. a short looking-reasonable piece of JavaScript code might whack the browser and force users to use “task manager” to shut it down

here is a sample of memory leak

 function onload(){
	var e = document.getElementById("xid");
	e.onclick = function(){}

this piece of code looks alright but memory leaking
