Modify Array Data With Indexes

Hints

Hint 1

Access the position of the array, and change it, like so:

var arr = [1, 2, 3, 4, 5];

arr[0] = 6; // Now, the array is [6, 2, 3, 4, 5]
arr[4] = 10; // Now, the array is [6, 2, 3, 4, 10]

The important concept here is that arrays are mutable. This means that they can be changed easily.

I am having problems with this challenge. Here is what I’ve done:

var myArray = [1,2,3];
ourArray[0]=3;

Wouldn’t that modify the array, so that the array would read [3,2,3]?
