Mars Rover Kata Scala

Mars rover code kata solved using Scala.

Goals

• be pragmatic, don't overdo the solution
• use the type system to your advantage
• make the "core" immutable
• use Scala language's strengths (pattern matching etc)
• separate concerns (parsing/moving/etc)

Takeaways

• Bugs easily occurred using the same primitive for different semantics (e.g. swapping x for y coordinate)
• Tests caught these bugs early
