some code clean up

[agchou]

Hey guys!

First of all, just want to say thank you for creating such an amazing framework. I'm currently working hard to become a full-stack javascript developer and have been recently learning express.

While reading through the code many times, I noticed some inconsistencies in the formatting (especially with the "Module Dependencies") and thought it could be a chance for me to try and become involved in open source. In this commit I formatted the "Module Dependencies", moved the export to the top with comments, and added comments to the initialize function for Layer.

If this is not acceptable please let me know if I can help out in any other way. I am willing to go through all files and format "Module Dependencies" or any other mundane tasks you need completed. Thanks so much for reading—I am greatly inspired by you all!

yeah this is how TJ writes code, but roman and i don't really follow this paradigm. you're just repeating the code without explaining any "why"s. if it made the code any more understandable (i.e. explanations), then i'd merge it, but it's just stylistic right now so i'm meh. consistency is nice though

[agchou]

I see and definitely agree about the comment for initializing. If you want me to go through and change for consistency I will gladly.

[agchou]

Removed Layer initialization comment I added. Added a few missing semicolons, removed unnecessary spacing, and changed module dependencies to be consistent.

@defunctzombie do you like single vars or multiple vars? i like multiple vars because of easier diffs and var can be typed with your left hand while your right hand does other things.

[defunctzombie]

I'm a multiple var kind of guy but I typically remain consistent with the project, just messed up with this file :)

[jonathanong]

i think TJ switched to multiple vars as well. i've been writing code as multiple vars as i change stuff, but i didn't want to go through every file and switch it.

@agchou do you want to switch the style to multiple vars? i'm not sure how big the diff is, but if it's too big, multiple vars is fine. consistency ftw!

[agchou]

@jonathanong yah I'll switch it to multiple vars as long as @defunctzombie and other are cool with it. Just to clarify I am going to switch files from single var (many commas) to multiple vars (1 per declaration).

[agchou]

Let me know if you want me to go through any of the other directories (examples, test, etc.). Thanks for giving me the opportunity to help out!

[jonathanong]

looks good. we can merge this PR for now and feel free to open up more PRs.

can you squash the commits?

[agchou]

@jonathanong done! will keep chugging away when I have time to go through the remaining files.

btw git is probably the most annoying thing I've encountered while learning software engineering... why, just why.

[jonathanong]

it's annoying at frist but it all makes sense when you understand it
