Gain insights into writing cleaner, modular, scalable JavaScript code through OOP. Explore basics to advanced concepts like prototypal inheritance, method overriding, and ES6 features.

Learn to write cleaner, more modular, and more scalable code in JavaScript by gaining mastery of Object Oriented Programming (OOP). 

You'll start with the basics of object-oriented programming and build up to more advanced concepts such as prototypal inheritance, prototype chaining, method overriding and mixins. Along the way, you'll learn how each concept applies to JavaScript's sometimes unique way of handling things. You'll also see how various JavaScript features make it particularly convenient for OOP, with particular emphasis on changes introduced in ES6.

This course is filled with hands-on coding challenges, playgrounds, snippets, and illustrations to keep things interactive.

# Problem Statement
This exercise has **two parts**.

## First Part
The shop has decided to offer a **10%** discount on `Cheese`. In the first part, you are required to write a **set** function `setPrice` which updates the `price` after computing the discount.

## Second Part
In the second part, you are required to implement the same functionality but this time you need to make the function using the `set` keyword instead. As an addition, you also need to call `setPrice` in the `testFunc` function given.

>**Note:** We are only using the `testFunc` function for testing purposes, so there's no need to worry. Just call your function there.


## Sample Input

20

## Sample Output

18

>**Note:** The skeleton function for `setPrice` is given in both code tabs. Right now, it is not being passed any parameters. You need to pass it appropriate *parameter/parameters*, so use appropriate *keywords* and write the code for implementation as well. 





In this exercise, you will be required to write a set function both with and without the set keyword.
