I want the man object inherits from the person object. I could have done it using the new operator, but it should work with `Object.create`. But why it is not working? The `console.log` says `undefined` instead of the expected `hello`.

```js
function person() {
    this.say="hello";
}

function man() {
    this.name="John Miler";
}

man.prototype = Object.create(person);

var Johnny = new man();

console.log(Johnny.say);  
```
