Now that we have set up our game environment, were ready to add our rover and the hazards players will need to avoid. // Input: M The output for each rover should be its final co-ordinates and heading. I am working on Mars to Rover program with JavaScript and I already finished iteration 1 that allows my rover to move to all directions in 2 dimensions (x,y). It may help to put the rover and the hazards, along with their rules for moving, in one loop, but this can be done across multiple loops or even across multiple libraries.
