Constructor function fails to display accurate outcomes

Question

Constructor function fails to display accurate outcomes

Just beginning my coding journey here. Attempting to create a car object and its instances. Here's the code snippet:

  function Car(name, speed) {
        this.name = name;
        this.speed = speed;
        this.describe=describeCar;
    };


    function describeCar(){
        document.write("The Full name is " + this.name + " and the top speed is " + this.speed);
    };

    var mercedes = new Car("Mercedes benz", 233); // Instance of Object
    var bmw = new Car("British motor Works", 260); // Instance of Object
    mercedes.describeCar();

However, upon running the code, nothing appears in the browser. I'd really appreciate any guidance on what I might be missing or doing incorrectly. Thanks a bunch!.

Answer №1

You are linking the function describeCar to the describe property of the object Car, allowing you to use it in this way:

mercedes.describe();

function Automobile(brand, velocity) {
        this.brand = brand;
        this.velocity = velocity;
        this.info = describeAuto;
    };

    function describeAuto(){
        document.write("The brand is " + this.brand + " and the top speed is " + this.velocity);
    };

    var toyota = new Automobile("Toyota", 180); // Instance of Object
    var honda = new Automobile("Honda", 205); // Instance of Object
toyota.info();

honda.info();

Remember to call the class method name instead of the specified one.

function Automobile(brand, velocity) {
        this.brand = brand;
        this.velocity = velocity;
        this.info = describeAuto;
    };

    function describeAuto(){
        document.write("The brand is " + this.brand + " and the top speed is " + this.velocity);
    };

    var toyota = new Automobile("Toyota", 180); // Instance of Object
    var honda = new Automobile("Honda", 205); // Instance of Object
toyota.info();

honda.info();

When using the describeCar function, remember to include parentheses when calling it and use "this" as a reference if you intend to utilize it within the constructor:

function Car(name, speed) {
    this.name = name;
    this.speed = speed;
    this.describe=this.describeCar();
};

Car.prototype.describeCar = function(){
    return "The Full name is " + this.name + " and the top speed is " + this.speed;
};

var mercedes = new Car("Mercedes benz", 233); // Object Instance
var bmw = new Car("British motor Works", 260); // Object Instance
document.write(mercedes.describe);

If you only require the function output, simply call the function without using it in the constructor:

function Car(name, speed) {
    this.name = name;
    this.speed = speed;
};

Car.prototype.describeCar = function(){
    return "The Full name is " + this.name + " and the top speed is " + this.speed;
};

var mercedes = new Car("Mercedes benz", 233); // Object Instance
var bmw = new Car("British motor Works", 260); // Object Instance
document.write(mercedes.describeCar());
