简单的问题.我为什么要这样做......

var Person = function(name) {
    this.name = name;
    this.sayHello = function(){
        console.log('Hello, my name is ' + this.name); // <-- 
    }
};

代替...

var Person = function(name) {
    this.name = name;
    this.sayHello = function(){
        console.log('Hello, my name is ' + name); // <--
    }
};

我没有发现他们表现不同的情况.
