Welcome to my Advent of Code 2021 contribution! The solutions are written in JavaScript using Node.js. When writing the solutions code I primarily aim for readability but try to always keep performance considerations in mind (thought the latter strongly depends on how much time I can spend). Happy reading!
Advent of code is made by Eric Wastl.
[It is] an Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like. People use them as a speed contest, interview prep, company training, university coursework, practice problems, or to challenge each other.
For more information see about Advent of Code.
For running the code you need the Node.js runtime installed. Run the code via
node dayXX/partX.js
