How does a jQuery instance appear as an array when called in console.log?

When entered into a JavaScript console, a jQuery object appears as an array. However, it\'s still an instance of the jQuery object.

var j = jQuery();
=> [         


        

Answer 1

I believe they have something like that:

// Adding items to an object like an Array:
var myObject = {splice : Array.prototype.splice};

Array.prototype.push.call(myObject, 1, 10, "foo");

// Getting items from an object like an Array:

alert(Array.prototype.slice.call(myObject, 0));

console.log(myObject);

alert(myObject);
