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

You need to *iterate* through the object and change the value of:

* `name` to **Bottle**
* `madeIn` to **China**

You need to do the above-mentioned task in the `set` function given below. We are using that function for testing purposes only, so no need to worry. Just write the implementation code there.

>**Note:** For more practice, try solving this question using both *dot notation* and *square brackets* to access properties of the object. 



In this exercise, you will be required to iterate through the properties of an object.
