Array Iteration

While attempting to explain JavaScript's reduce method on arrays, conceptually, I came up with the following - hopefully it's helpful; happy to tweak it if anyone has suggestions.

Intro

JavaScript Arrays have lots of built in methods on their prototype. Some of them mutate - ie, they change the underlying array in-place. Luckily, most of them do not - they instead return an entirely distinct array. Since arrays are conceptually a contiguous list of items, it helps code clarity and maintainability a lot to be able to operate on them in a "functional" way. (I'll also insist on referring to an array as a "list" - although in some languages, List is a native data type, in JS and this post, I'm referring to the concept. Everywhere I use the word "list" you can assume I'm talking about a JS Array) This means, to perform a single operation on the list as a whole ("atomically"), and to return a new list - thus making it mu

#Set up an RPi Audio project

Use the following instructions to prepare your RPi's SD Card for an audio project.

###Install an operating system. You first need to install an operating system on your RPi. Raspian should work fine. If you're using a monitor, keyboard and mouse, using an install manager is the easiest way. Just follow the instuctions for installing NOOBS.

If you are developing headless, follow the instructions for downloading and installing Raspian. You'll also need to login via ssh or a console cable. If you're on Yosemite on a Mac, [this post](http://zittlau.ca/fix-usb-serial-console-on-raspberry-
