// Random inheritance example

function Vehicle(color) {
  this.color = color
}

Vehicle.prototype.move = function() {
  // Do some stuff here
}

function Car(color, drivetrain) {
  // Calling the Vehicle constructor
  Vehicle.call(this, color)
  this.drivetrain = drivetrain
}

// Inherit the prototype, do not use new here.
// Call super constructors in the constructor.
// Optionally, you can add the constructor as an non-enumerable property here, 
// but you may have a hard time shim'ing this in older browsers.
Car.prototype = Object.create(Vehicle.prototype)


var car = new Car('red', '4wd')
console.log(car instanceof Car) // true
console.log(car instanceof Vehicle) // true
console.log(car.drivetrain) // '4wd'
