7. sort Exercise make it so it sorts on last name

In your video you still sort on the first name of the array but you called it `aLast` and `bLast` but they where in the first position of the array like this: `const [aLast, aFirst]` when changed to `const [aFirst, aLast]` it will filter on the second part of the array. There for it will sort on the last name. 

To bad there is no way to pull request your video.
