寄生式继承（用于共享引用类型的值，与原型式类似）
function createAnother(original){ var clone = Object(original); clone.sayHi = function(){ return "Hi"; }; return clone; } var person = { name: "Oliver", number: [13,21,31,1] }; var anotherPerson = createAnother(person); anotherPerson.number.pop(); console.log(anotherPerson.sayHi() + anotherPerson.number); //Hi13,21,31 console.log(person.number); //13,21,31
