# Robot Simulator
Write a robot simulator.
A robot factory's test facility needs a program to verify robot movements.
The robots have three possible movements:
- turn right
- turn left
- advance
Robots are placed on a hypothetical infinite grid, facing a particular
direction (north, east, south, or west) at a set of {x,y} coordinates,
e.g., {3,8}, with coordinates increasing to the north and east.
The robot then receives a number of instructions, at which point the
testing facility verifies the robot's new position, and in which
direction it is pointing.
- The letter-string "RAALAL" means:
- Turn right
- Advance twice
- Turn left
- Advance once
- Turn left yet again
- Say a robot starts at {7, 3} facing north. Then running this stream
of instructions should leave it at {9, 4} facing west.
## Setup
Go through the setup instructions for JavaScript to
install the necessary dependencies:

## Making the Test Suite Pass
Execute the tests with:
jasmine <exercise-name>.spec.js
Replace `<exercise-name>` with the name of the current exercise. E.g., to
test the Hello World exercise:
jasmine hello-world.spec.js
In many test suites all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
changing `xit` to `it`.
## Source
Inspired by an interview question at a famous company.
## Submitting Incomplete Solutions
It's possible to submit an incomplete solution so you can see how others have completed the exercise.
