Array pop() shift()

if you wanted to remove the last item in an array you would want to use pop() method. This removes the last item from an array but also returns it.

example:

var array = [1, 2, 3];
var last = array.pop([2]);

This removes the last item from the array "3" then save's 3 in the var last.  If you wanted to use it later.

Similarly the shift() method does the same for the beginning of an array.
