Step One: Watch Mary Rose Cook Live Codes Space Invaders from Front-Trends. (The second worst conference name ever?)

Step Two: Fork this gist.

Step Three: Respond to this question in your fork: What is one approach you can take from this Mary's code and implement in your project?

Step Four: Totally Optional: take a look at some of the other forks and comment if the spirit moves you.

Step One: Watch Writing Testable JavaScript - Rebecca Murphey from Full Frontal 2012 (award for worst conference name ever?)

Step Two: Fork this gist.

Step Three: Respond to this question in your fork: Consider the four responsibilities that Rebecca lists for client side code (hint: they're color coded). Respond below with your thoughts. Did any of the responsibilities that she lists surprise you? Do you feel like you mentally split your client side code in IdeaBox and other past projects into these responsibilities?

Step Four: Totally Optional: take a look at some of the other forks and comment if the spirit moves you.

**Step One**: Watch [Sorting Algorithms in JavaScript](https://www.youtube.com/watch?v=uRyqlhjXYQI)

**Step Two**: Fork this gist.

**Step Three**: Respond to this question in your fork: "What are some of the balances and trade offs between different sorting algoritms?"
Speed and 'stability' (relative order of sort-equivalent elements) are great, but sometimes the need for local resources (like memory) would be too great to use a sort that would be awesome if they were readily available.

**Step Four**: _Totally Optional_: take a look at some of the other forks and comment if the spirit moves you.

I can explain the difference between function declarations and function expressions. Sort of. 2

I can explain what the value of this is in a normal function. 3

I can explain what the value of this is when called from the context of an object. 3

I can explain how to explicitly set the value of this in a function.

Array Prototype Methods

I understand that functions in JavaScript can take any number of arguments. yup

I can describe the similarity between blocks in Ruby and anonymous functions in JavaScript. yup

Where are the methods available to all arrays (e.g. forEach, map, etc.) defined? Array.prototype
