underscore中 _.restArguments 用法:
var raceResults = _.restArguments(function(gold, silver, bronze, everyoneElse) { console.log(everyoneElse); }); raceResults("Dopey", "Grumpy", "Happy", "Sneezy", "Bashful", "Sleepy", "Doc");
_.create
_.create 方法非常简单,根据你给的原型(prototype),以及一些 own properties,构造新的对象返回。
举个简单的例子:
var Person = function() {}; Person.prototype = { show: function() { alert(this.name); } }; var me = _.create(Person.prototype, {name: 'hanzichi'}); console.log(me);
undercore 的实现思路也大抵如此。
