Construct JavaScript Objects with Functions

Using constructors it is easy to create new objects using a blueprint or constructor. The declaration syntax is a little different but still easy to remember.

// Let's add the properties engines and seats to the car in the same way that the property wheels has been added below. They should both be numbers.
var Car = function() {
  this.wheels = 4;
  this.engines = 1;
  this.seats = 1;
};

var myCar = new Car();
