/*
MAKE UNIQUE OBJECTS BY PASSING PARAMETERS TO OUR CONSTRUCTOR
The constructor we have is great, but what if we don't always want to create 
the same object?

To solve this we can add parameters to our constructor. We do this like the following 
example:

var Car = function(wheels, seats, engines) {
  this.wheels = wheels;
  this.seats = seats;
  this.engines = engines;
};
Now we can pass in arguments when we call our constructor.

var myCar = new Car(6, 3, 1);

This code will create an object that uses the arguments we passed in and 
looks like:

{
  wheels: 6,
  seats: 3,
  engines: 1
}
Now give it a try yourself! Alter the Car constructor to use parameters to assign 
values to the wheels, seats, and engines properties.

Then call your new constructor with three number arguments and assign it to myCar 
to see it in action.
*/
var Car = function(wh, se, eng) {
  //Change this constructor
  this.wheels = wh;
  this.seats = se;
  this.engines = eng;
};

//Try it out here
var myCar = new Car(4, 7, 2);
console.log("What does myCar look like? ", myCar);
