Advent of TypeScript 2023

Advent of TypeScript is a series of progressively more difficult TypeScript challenges, which need to be solved entirely within the type system.

You can play Rock, Paper, Scissors in day 17, write ASCII art in day 20, play Tic-Tac-Toe in day 21, and play Connect 4 in day 23.

These are my solutions to the December 2023 challenges.
