function Student(n) { let name = n; this.say = function () { console.log(name)
}
} let xiaoming = new Student('xiaoming') let xiaohong = new Student('xiaohong')
xiaoming.say()
xiaohong.say() function Student(n) { this.name = n; this.say = function () { console.log(this.name)
}
} let xiaoming = new Student('xiaoming') let xiaohong = new Student('xiaohong')
xiaoming.say()
xiaohong.say()这两行代码输出都是:xiaomingxiaohong那么他们的区别是什么? let name 这个变量存储在哪?第一个代码段是因为闭包才使得输出不同吗?
