Why is it possible to query jQuery('div') like an array?

Question

I got another question regarding jQuery\'s architecture. $(\'div\') constructs a new jQuery object:

$(\'div\') instanceof jQuery; /         


        

Answer 1

jQuery objects are array-like objects.

An array-like object is an ordinary object that has the same properties that an array does.
An array like object has a length property set to a positive integer, and properties named 0, 1, ... length − 1 containing the array objects.
