JavaScript is one of the most popular languages used by programmers all around the world. In this course, you'll be introduced to the Object-Oriented Paradigm of JavaScript. The course will discuss OOP in both, ES5 and ES6 versions of JavaScript. It begins with a basic introduction to what Object-Oriented programming is, followed by its comparison to other languages. It then introduces the new  OOP features available in ES6 version and compares it to the ES5 version. The course then discusses objects in JavaScript followed by the use of function as objects in OOP. It goes over the interesting concepts of prototype objects, data encapsulation, and classes. It then delves into the more complex concepts of inheritance in both the versions, including prototypal inheritance, prototype chaining, method overriding and mixins. The course is filled with interesting illustrations to help in your understanding of the concepts as well as numerous quizzes and exercises to help you practice.

# Problem Statement

In this exercise, two object literals, `Person` and `Teacher` are given. 

Define the following properties in the `Teacher` object:

* `name` and set is as `Amy`.

* `age` and set is as `28`.
$$$$
Define the following properties in the `Teacher` object:

* `subject` and set it as `Maths`

* `grade` and set it as `8`

Next you have to set `Person` as the *prototype* of `Teacher` so that its properties can be accessed in `Teacher`.

# Sample Input
The following will be accessed from the `Teacher` object: 
```
name
age
subject
grade
```

# Sample Output
```
Amy
28
Maths
8
```




In this exercise, you have to implement prototypal inheritance between two objects, Person and Teacher.

Exercise 1: Who's the Teacher?
