How to represent a simple rectangle in class with JavaScript

Answer 1

class Rectangle {
    constructor(height, width) {
        this.height = height;
        this.width = width;
    }
    get area() {
        return this.height * this.width; 
    }
    *getSides() {
        yield this.height;
        yield this.width;
        yield this.height;
        yield this.width;
    }
}

const rect = new Rectangle(7, 13);

console.log(rect.area);
console.log([...rect.getSides()]); 


      
/*
run:
      
91
[ 7, 13, 7, 13 ]

*/
