CoffeeScript is JavaScript →
I really, really, really hate hearing excuses from other developers about why they are unable to learn or use CoffeeScript. This article, CoffeeScript is not a language worth learning, does a great job of putting the CoffeeScript vs JavaScript issue into perspective. If you haven’t read it yet, you absolutely need to stop what you’re doing and read it now.
The bottom line? CoffeeScript is awesome, so stop making excuses and start making great software instead.
