Discussion on: Tips: How to get last element of an array in javascipt

[Sakib Ahmed]

pop() method removes the last element from an array and returns that element. This method changes the length of the array.

Cool, i knew a little about the pop() method but now is more clear to me.

Here is a small example of this

var fruits = ['apples', 'oranges', 'grapes'];
var myLastFruit = fruits.pop();
console.log(fruits, myLastFruit);

This would log:

Array [ "apples", "oranges" ] grapes

As you can see 'grapes' now doesn't form part of the fruits variable but at the same time the pop() method returns the last item of the array. So clearly, if someone is going to use this method must be aware of this.
