Shape, using the new class syntax¶

Here, we'll use the new class syntax:

class Shape {
    constructor(color) {
        this.color = color;
    }
    getColor() {
        return this.color;
    }
    setColor(color) {
        this.color = color;
    }
    toString() {
        // using the new template strings
        return `[A ${this.color} ${this.constructor.name}]`;
    }
}

var s1 = new Shape("red");
console.log("s1 is "+s1.toString());     // Look in the JS console
