In jQuery, what is $ .fn. I mean?

Question

In jQuery, that $ .fn. I mean? I looked at it on google but did not find specific examples.

$.fn.something = function{} 

Answer 1

This allows you to extend jQuery with your own functions.

For example,

 $.fn.something = function{} 

will allow you to use

 $("#element").something() 

$.fn also synonymous with jQuery.fn , which can simplify Google searches.

Answer 2

It is described in detail here:

Why does jQuery do this: jQuery.fn.init.prototype = jQuery.fn?

But, nevertheless, $.fn is an alias for $jQuery.prototype
