TypeScript solutions to various coding exercises, organized into packages by origin. Some may have been specifically intended to be solved using TypeScript, but most will be language-agnostic.
Every exercise is tested using Jest and all examples provided are used as test cases.
Though I would have preferred Mocha + Chai, or Jasmine, because Jest is specialized for React, everyone else seems stuck on Jest, and I'd rather not have to mess with their tests when I copy them in.
