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

A *constructor function* `SquareSum(num1,num2,num3)` is provided which takes three numbers as properties. You have to initialize them. The constructor function also contains a method `squaresum()`. Implement it in a way such that it computes the square of the three numbers and returns their sum.

### Sample Input

2, 3, 4
