Long Live CoffeeScript and Long Live ES6

Clearly ES6 is a huge improvement over ES5, and tools like [6to5][] allow us to use these cool features now. I was reading [Replace CoffeeScript with ES6][replace coffeescript] by [Blake Williams][] and thought it was a great summary of how ES6 solves many of the same problems that CoffeeScript solves; however I'd like to comment on a few of Blake's points and talk about why I'll be sticking with CoffeeScript.

Classes

Classes in ES6 (like many of the syntax changes in ES6) are very similar to the CoffeeScript equivalent. To support browsers that are not fully ES5 compliant (e.g. IE8-), however, we still can't really use getters/setters, so ignoring these the comparison is:

Notes on installing the door-controller

DO NOT FOLLOW THESE NOTES, THEY ARE HACKS!

Do not install node from apt, install v0.10.x (x = 28)

Use gpio-admin from pull request #6 romilly/quick2wire-gpio-admin#6

Make similar changes to pi-gpio node module

I'm often asked why I still use CoffeeScript rather than ES6/7. Well, in truth I use both, but I do still prefer CoffeeScript for the following reasons:

• Correctly trimmed multiline strings (ES6 includes the indentation because it doesn't have significant whitespace)
• Existential operator (a?.b; b?(); a?.b?() and of course a ? b)
  • a ? b is more appropriate than a || b if "" or 0 are values of a you wish to persist
  • (a && a.b && typeof a.b === 'function') ? a.b() : undefined doesn't quite have the same ring to it as a?.b?()
• Significant whitespace
  • (a personal preference, but since you already lay your code out sensibly why do you need the additional visual distraction of braces?)
• Convenient shorthand for common things (-> (regular non-bound function), @ (this.), :: (.prototype.))
• in to check if something in a list
