Display git branch in bash prompt

# If you work with git, you've probably had that nagging sensation of not knowing what branch you are on. Worry no longer!
export PS1="\\w:\$(git branch 2>/dev/null | grep '^*' | colrm 1 2)\$ "
# This will change your prompt to display not only your working directory but also your current git branch, if you have one. Pretty nifty!
# ~/code/web:beta_directory$ git checkout master
# Switched to branch "master"
# ~/code/web:master$ git checkout beta_directory

* Idea from Scott Gonzalez
* to use, place attributes on an already-functional anchor pointing to content

* Replace: <a href="..." data-replace="articles/latest/fragment">Latest Articles</a>
* Before: <a href="..." data-before="articles/latest/fragment">Latest Articles</a>

Shim status of ES6

ES6 what can be shimmed and what not.

Currently only lists things that can be shimmed or are experimentally implemented

Note that for any kind of decent ES6 support we need an ES6 transpiler. A few projects are attempting this [Reference SO question][3]

ID - a unique ID/name generator for JavaScript
View ID.js
// Generate unique IDs for use as pseudo-private/protected names.
// Similar in concept to
// <http://wiki.ecmascript.org/doku.php?id=strawman:names>.
//
// The goals of this function are twofold:
//
// * Provide a way to generate a string guaranteed to be unique when compared
// to other strings generated by this function.
// * Make the string complex enough that it is highly unlikely to be
// accidentally duplicated by hand (this is key if you're using `ID`
