Creating array numbers, checking array for duplicates, function composition in JS. Grab bag, man!

This video is kind of weird. There are a few algorithms in it - one for creating an array of random numbers, one for checking to see if that array has duplicates (this is done in an O(N) time), and then creating a compose function to run both. Not bad.

Nice vid! Last part was a little quick and the function at the end was not very readable (at first glance any way)
