Solution Review: Prototypal Inheritance

function Human(name, age) {
    this.name = name;
    this.age = age;
};
function Man(name,age) {
    Human.call(this, name, age);
};
Man.prototype = Object.create(Human.prototype);
Man.prototype.constructor = Man;
function check(){
    var obj = new Man("Tommy Tan",20);
    console.log(obj.name) 
    console.log(obj instanceof Human) 
}
check()
