Use of .on method over the .delegate method

Question

I gone through the different description provided for the .on() method or .delegate() method. But unable to clarify the actual need of .on() over .delegate().

I just came out with only one difference which of syntax nothing else.

.on() -- function( types, selector, data, fn ) .delegate -- function( selector, types, data, fn )

Any other difference?

Answer 1

Actually, delegate() uses on(), internally.

The jQuery delegate() method's source code:

function (selector, types, data, fn) {
    return this.on(types, selector, data, fn);
}

So no, other than calling one less function, there is no difference. delegate() is there purely to better differentiate between dynamically and statically added event listeners, should you want to.
