Replace .map() with .forEach() where preferable

[bharbron]

Downside of learning as I code: using some things incorrectly. There's a lot of places in code where I'm iterating over arrays using .map() where I should be using .forEach() (or maybe even .reduce()) instead. Basically, it's anyplace where I'm not actually trying to build a new array, I'm just trying to perform an action on each item in an array.

Fix this! Bad javascript abounds!

Additionally, should look at replacing almost every instance of for loops with .map() or .forEach() (whichever is appropriate to the use case). This is less critical and more for code cleanliness.
