Underscore.js与nodejs相结合
今天发现这个Underscore.js，文档说http://documentcloud.github.com/underscore/
引用
Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby)。
提供了许多类似ruby风格的函数，这是我所喜欢的。
看几个例子。
安装
引用
npm install underscore
在nodes.js中测试
_ = require 'underscore'
_.each , (num) -> console.log(num)#=>1 2 3
_.each
one : 1
tow:2
three:3
(num,key) ->
console.log "#{key}:#{num}"
a1 =_.map , (num)-> num * 3
_.each a1, (num) -> console.log(num)#=>3 6 9 12
