Question

I know how to initliaize one but how do add I items to an Array? I heard it was push() maybe? I can’t find it…

Answer 1

For JavaScript arrays, you use push().

var a = [];
a.push(12);
a.push(32);

For jQuery objects, there’s add().

$('div.test').add('p.blue');

Note that while push() modifies the original array in-place, add() returns a new jQuery object, it does not modify the original one.
