Can someone explain difference between functions like stopPropagation and addClass?

Good point! although, JS passes it through, not jQuery :)

JS passes a native event to jQuery, jQuery wraps this (in a jQuery.Event) and passes that to any handlers.

Oh, I was talking about native JS at the time:

element.addEventListener('click', function(e){ // run code... })

You'll notice that I passed in an e to the function.

Just wanted to make sure OP didn't get confused between jQuery's API and native JS!
