We are also able to create objects using constructor functions.
A constructor function is given a capitalized name to make it clear that it is a constructor.
Here's an example of a constructor function:
var Car = function() { this.wheels = 4; this.engines = 1; this.seats = 5; }; In a constructor the this variable refers to the new object being created by the constructor. So when we write,
this.wheels = 4;
inside of the constructor we are giving the new object it creates a property called wheels with a value of 4.
You can think of a constructor as a description for the object it will create.
Have your MotorBike constructor describe an object with wheels, engines and seats properties and set them to numbers.
var Car = function() {
this.wheels = 4;
this.engines = 1;
this.seats = 5;
};
// Only change code below this line.
var MotorBike = function() {
this.wheels = 2;
this.engines = 1;
this.seats = 1;
};
/*это дает нам создание объекта, типа такого: {"wheeels: 2, engines: 1, seats: 1"}*/
