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);
Enter fullscreen mode Exit fullscreen mode

This would log:

Array [ "apples", "oranges" ] grapes
Enter fullscreen mode Exit fullscreen mode

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.
