Array index

In the video when Andrew typed days.push("Tuesday") it returned 2 shouldn't it return 1 since arrays begin from 0

From w3schools

The push() method adds new items to the end of an array, and returns the new length.

So the index for "Tuesday" may be 1 but the new length of the days array is 2.
