How is jQuery's $ a function and an object?

Question

I mean object as in {} [object Object]. How does it do $(selector) and $.fn.init at the same time?

Can you give me a simple ex

Answer 1

It is an object.

$ holds different functions.

You can test this yourself by making your own object:

var $ = {
     select: function(id){return document.getElementById(id);}
}

function $(id){
      return $.select(id);
}
