Do you pronounce 'babel' in the same way? No
- Follow Up Question: Will you now? Yaaas!

What is an example of why/where you might use recursion? You can use it in most cases where you would otherwise nest for/ while loops. In this video, the author uses it to create a search tree from an array of objects with like attributes.
Mary Rose Cook Live Codes Space Invaders from Front-Trends.
- I really like Mary's use of filter to check for the presence of fellow invaders within a firing path and block the action if the result was greater than 0. I think that we could use a similar approach to track our snake's body and prevent backward movement over itself.
- I also like how object oriented everything was; right now our game is a long method that is called at page-load but, we should abstract it out into instances of a "Game" module which might also help with some reset issues we are hitting now.
Consider the four responsibilities that Rebecca lists for client side code (hint: they're color coded).
According to this talk, client side code is responsible for: Presentation & Interaction; Data/ Server Communication; Application State and Setup
-
Did any of the responsibilities that she lists surprise you?
Not necessarily; coming out of Rails, getting used to putting all of those responsibilities like setup, in particular, feels a bit strange but, working with and having seen some of the projects that we will do and that will force us to manage all of these things in our client-side code it makes sense.
Read Node.js, Require and Exports and Organize Your Code with RequireJS
- In the context of Node, what is a
module
?
"Modules are small chunks of your application that serve a specific purpose"... In the context of Node, a module is a set of objects with a given purpose in the program that are stored together and accessible within a one file. These act similarly to a module or class in Ruby in that they serve to group data and functions which are callable from other files through importing and exporting.

**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?" | |
**Step Four**: _Totally Optional_: take a look at some of the other forks and comment if the spirit moves you. |
- ES6 is the newest update to the Javascript and is currently being incorporated into most major JavaScript engines.
- Transpilation is the process of converting code to an updated/ similar language. Because ES6 is not fully supported yet, it must be converted on the client-side.
Looking at the ES6 Features link below, discuss one update from ES5
and if it seems useful/superfluous.
- String interpolation seems pretty exciting! While not necessarily a needed feature, coming form Ruby, it would be really great to have.
