A Message object has a name and contains several Command objects. Build a game loop that will determine the rules for when the game is active and how your rover will move. While the rover is meticulously monitored and controlled, the dangerous conditions on Mars cant always be avoided. 'MODE_CHANGE' and 'MOVE' are passed in as the commandType. Jasmine specs are located alongside the modules they're testing, and follow the naming convention *_spec.js. of instructions telling the rover how to explore the plateau. JavaScript Tutorial Through Katas: Mars Rover - Technology Conversations the details of the types when we get to the Rover class and tests. What are the parts of a Mars rover?
