Fibonacci with Generators

JavaScript just got yield? Cute.

Indentation 😨😨😨

@Brolls As far as I know, they've had it for a long while.

Here's a Haskell one-liner for you:

fibList = 0 : 1 : zipWith (+) (fibList) (tail fibList)

Yes, this is a list of the entire Fibonacci sequence. (I know this is a classic and overused example but couldn't resist lol). It's a very instructive exercise to figure out how this works, it's both lazy and self-referential.

I know the classic way of defining Fibonacci is recursively, but I'm really not a fan of how everyone only write it recursively. It's not the best way and tends to break all the time!
