🎅 🎄 ⛄ ✨ Solutions for Advent of Code 2020 in TypeScript

Advent of Code 2020 🎅 🎄 ⛄ ✨

Advent of Code using TypeScript.

There's no need to build anything. Source files are transpiled and cached on-the-fly using esbuild-runner with pretty much zero overhead. Running the code for a certain day, will:

• download the input if needed
• test any examples for each part
• test the answer (if availble) for each part
• measure the performance and update the benchmark section of this readme

⚡ Benchmark

My personal goal for this year is to solve all puzzles within 25ms total, so an average of 1ms per puzzle.

edit: never mind 😂
