Moving to ES6 from CoffeeScript

I fell in love with CoffeeScript a couple of years ago. Javascript has always seemed something of an interesting curiosity to me and I was happy to see the meteoric rise of Node.js, but coming from a background of Python I really preferred a cleaner syntax.

In any fast moving community it is inevitable that things will change, and so today we see a big shift toward ES6, the new version of Javascript. It incorporates a handful of the nicer features from CoffeeScript and is usable today through tools like Babel. Here are some of my thoughts and issues on moving away from CoffeeScript in favor of ES6.

While reading I suggest keeping open a tab to Babel's learning ES6 page. The examples there are great.

Punctuation

Holy punctuation, Batman! Say goodbye to your whitespace and hello to parenthesis, curly braces, and semicolons again. Even with the advanced ES6 syntax you'll find yourself writing a lot more punctuatio

	// Responsive Margin & Padding Shortcuts for Twitter Bootstrap 3.0
	// ---------------------------------------------------------------
	// This is an addition to Twitter Bootstrap that allows additional margin and padding shortcuts
	// for enhanced layout control purposes. It should be included after the bootstrap.less
	// import statement or precompiled as you see fit. It differs from bootstrap standards in
	// that for any given screen size it predetermines the margin/padding size. All you have to
	// do is specify the size you want xs,sm,md,lg, or xl. The exception is for items that you
	// want to be centered using auto left/right margins. This can be device responsive by
	// specifying mc-xs, mc-sm, mc-md, or mc-lg depending on when you want that behavior.
