Coffee(Script) Break

What?

CoffeeScript is a programming language that transcompiles to JavaScript. The language adds syntactic sugar inspired by Ruby, Python and Haskell to enhance JavaScript's brevity and readability, adding sophisticated features like list comprehension and pattern matching. CoffeeScript compiles predictably to JavaScript and programs can be written with less code, typically 1/3 fewer lines, with no effect on runtime performance. Since March 16, 2011, CoffeeScript has been on GitHub's list of most-watched projects, and as of today is the eleventh most popular language on GitHub.

...Additionally, Brendan Eich has referenced CoffeeScript as an influence on his thoughts about the future of JavaScript.

-- Wikipedia

Who?

Jeremy Ashkenas

A language that takes out the frustrating and overly verbose bits of JS, and provides a safer, briefer way to stick to the good parts...The idea is to write your source code as if it were an essay for a person to read, instead of a series of instructions for a machine to execute.

How?

[terrence_lee@BAM-024206-TL~]$ npm install -g coffee-script

Why?

Readability, Brevity, Consistency
