HackerRank Day 4: Classes 10 days of javascript solution

In this Day 4: Classes 10 days of javascript problem you need to Create a Polygon class that has A constructor that takes an array of integer values describing the lengths of the polygon's sides. A perimeter() method that returns the polygon's perimeter.

HackerRank Day 4: Classes 10 days of javascript problem solution.

/*
 * Implement a Polygon class with the following properties:
 * 1. A constructor that takes an array of integer side lengths.
 * 2. A 'perimeter' method that returns the sum of the Polygon's side lengths.
 */
class Polygon{
    constructor(sides){        
        this.sides = sides
    }
    perimeter() {
        return this.sides.reduce(function add(a,b){return a+b;})
    } 
}


const rectangle = new Polygon([10, 20, 10, 20]);
const square = new Polygon([10, 10, 10, 10]);
const pentagon = new Polygon([10, 20, 30, 40, 43]);

console.log(rectangle.perimeter());
console.log(square.perimeter());
console.log(pentagon.perimeter());
