// 寄生组合式继承// 其基本思路是通过借用构造函数来继承属性，通过原型链的混成形式来继承方法，就是为了不必为了子类型的原型去调用父类型的构造函数function inheritPrototype(superPerson,person){  var prototype=Object.create(person.prototype);  prototype.construtor = superPerson;  superPerson.prototype = prototype;}function Person(name){   this.name = name;  this.frieds =  ["Jack", "John", "Kim"];}Person.prototype.getName = function(){  console.log(this.name);};function SuperPerson(name,sex){  Person.call(this,name);  this.sex = sex;}inheritPrototype(SuperPerson,Person);SuperPerson.prototype.getSex = function(){  console.log(this.sex);};var Tom=new SuperPerson("Tom","man");Tom.getName();//Tom
