An underappreciated benefit of computer programming "languages" is how human begins use them to communicate with other humans. Once you get two or more programmers working on a project, they have to be able to write code that the other programmer can readily understand. Programming languages advance this goal to varying degrees; assembly does it poorly, and so does obfuscated C or Perl. CoffeeScript, on the other hand, seems to have borrowed language features that enhance this human-to-human communication ability: significant whitespace, easily comprehensible object models, etc.
