What does fn in jQuery stand for?

Question

I know jQuery.fn is just an alias of jQuery.prototype, but what does "fn" stand for? Does it have a full name?

For example, "formal name"? "formal namespace"? I've no idea.

I'll add that in Basic, to define a function you wrote DEF FN :-) — xanatos, Commented Jul 18, 2012 at 13:04
@xan Obvious connection, since jQuery compiles down to BASIC... ;o))) — deceze, Commented Jul 18, 2012 at 13:05

fn as in f unctio n.

It is also the name of the formal parameter wherever a function is expected:

// Bind a function to a context, optionally partially applying any
// arguments.
proxy: function( fn, context ) {

They named it fn whoopee, but you can easily rename it. it does not have to be called fn

jQuery.fn is just an alias for jQuery.prototype (which just saves us time when coding such jQuery.fn.init.prototype = jQuery.fn = $.fn as such).

If you remember about prototypes functions in JavaScript Objects, then it would make total sense.

Remember, JQuery itself is an object.
This article can help you to better understand.

Thanks philippe, probably it's a shorthand for "function", but is there any official document for this information? Or, is it conventional?
