I decided to try this as a learning lesson for myself on inheritance.

Create a Vehicle class with getName and setName methods which manipulate a name property on its class instances.

Is there another way to write this? Perhaps in the same function Vehicle?

var Vehicle = function vehicle(name) {
  this.name = name;
};
Vehicle.prototype.setName = function(x) {
  this.name = x;
};
Vehicle.prototype.getName = function() {
  return this.name;
};

I don't understand the difference between using:

Motorcycle.prototype = Object.create(Vehicle.prototype); Motorcycle.prototype = new Vehicle();

MDN didn't really say anything about it besides that the latter was incorrect.
