我一直在学习有关node.js和模块的信息,似乎无法让Underscore库正常工作……似乎我第一次使用Underscore中的函数时,它会覆盖_对象,结果是我的函数调用。有人知道发生了什么吗?例如,这是来自node.js REPL的会话:
Admin-MacBook-Pro:test admin$ node
> require("./underscore-min")
{ [Function]
_: [Circular],
VERSION: '1.1.4',
forEach: [Function],
each: [Function],
map: [Function],
inject: [Function],
(...more functions...)
templateSettings: { evaluate: /<%([\s\S]+?)%>/g, interpolate: /<%=([\s\S]+?)%>/g },
template: [Function] }
> _.max([1,2,3])
3
> _.max([4,5,6])
TypeError: Object 3 has no method 'max'
at [object Context]:1:3

当我自己制作Javascript文件并将其导入时,它们似乎工作正常。Underscore库也许有一些特别之处?
