Question

I am trying to hide an element after 2000ms by the below code.

setTimeout($templateElement.hide(),2000);

I am the new one to jquery and java-script. I hope Anyone clear my doubts.

Answer 1

The code

setTimeout($templateElement.hide(),2000);

executes the $templateElement.hide() immediately and passes its return value (a jQuery object) into setTimeout. You may have meant:

setTimeout(function() {
    $templateElement.hide();
}, 2000);

…which passes a function reference into setTimeout, to be called two seconds later. That function then does the hide when it gets called.
