What is a jQuery Object?

Question

JavaScript kind of redefines what an Array means because an array is an object with a .length property and methods like .slice() and .join()<

Answer 1

the jQuery object is an object which has

• a length property
• numeric properties which reference the items from the select (0,1,2,3...)
• bindings to jQuery functions
• additional jQuery properties

The length and numeric properties allow the object to respond like an array. You can run it in a for loop or use functions like map or each on it.

I would recommend using your browser's debugger or Firebug and inspect a jQuery object. That will teach you a lot about how it is structured.
