"CoffeeScript is an attempt to expose the good parts of
Javascript in a simple way"
Características - indentação obrigatória - tudo é uma expressão -
é apenas javascript - mapeamento 1 x 1 (ideal) - não é um superset do javascript
Variáveis e escopo - sem “var” - variable safety -
globais explícitas
Funções - parâmetros entre parênteses - seta - corpo da
função
Funções
Funções splats defaults
Objetos - { ... } opcionais - vírgulas opcionais -
protege nomes reservados
Arrays indexOf
Range literals, slicing, splicing
Array de objetos
Condicionais

> 60 then passed else failed).push score for score in [49, 58, 76, 82, 88, 90] console.log "Happy Birthday #{if i is 3 then "dear Robert" else "to You"}" for i in [1..4] http://rosettacode.org/wiki/Category:CoffeeScript
Debug erros apontam para o source javascript futuro: source-mapping
