CoffeeScript este un limbaj de programare care este compilat in JavaScript. Nu exista un interpretator la runtime-ul aplicatiei. Fiind unul din successorii JavaScript, CoffeeScript incearca sa compileze JavaScript usor de citit si performant.
|
|
|
|
Mai cititi si [website-ul CoffeeScript](http://coffeescript.org/), care contine un tutorial complet Coffeescript.

# CoffeeScript este un limbaj de hipster.
|
|
# Se foloseste de trendurile multor limbaje moderne de programare.
|
|
# Comentarii sunt ca in Ruby sau Python.
|

|
Comentariile in bloc sunt create cu `###`, iar acestea sunt transformate in `/*` si `*/` pentru JavaScript
|
|
|
|
Ar trebuie sa intelegeti JavaScript pentru a continua cu acest ghid.

# Atribuirea valorilor:
|
|
numar = 42 #=> var numar = 42;
|
|
opus = true #=> var opus = true;
|
|
|
|
# Conditii:
|
|
numar = -42 if opus #=> if(opus) { numar = -42; }

|
|
# Functii:
|
|
laPatrat = (x) -> x * x #=> var laPatrat = function(x) { return x * x; }
