CamelCase

This project is aimed at helping you better understand how the type system works, writing your own utilities, or just having fun with the challenges.

Two notes here:

• The "capitalize" challenge should go before this one.
• The tests are a bit dumb IMO. This is my solution before I realized this fact:

type CamelCase<S> = S extends `${infer H}-${infer T}`
  ? `${H}${Capitalize<CamelCase<T>>}`
  : S;

This will handle all cases better. However, as you note in your solution, the tests won't allow this lol.

Edit: I just realized that this is literally the same as one of your intermediate steps. My bad heh.
