function Parent(name){
	this.name = name;
}

Parent.prototype.sayHello = function(){
	console.log("Hello " + this.name);
}

function Child(name) {
    Parent.call(this,name);
}

Child.prototype = Object.create(Parent.prototype, {
	constructor: {
	    value: Child,
	    enumerable: false,
	    writable: true,
	    configurable: true
	}
});

var c1 = new Child("c1");

c1.sayHello();　// Hello c1
