This is just all the answers I've been working on during the event of Advent of Code, 2020 edition.
Advent of Code 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.
In my case I chose JS to solve all the challenges.
Each puzzle is in its own folder. Each folder represents a day.
Inside each day, there is always an input.js file with the dataset you need to use in order to solve the puzzle.
In addition, each puzzle has two different parts. There are always two folders: part1 and part2 inside each day with the instructions and question you need to solve to complete that part.
Finally, to help you achieve your goal, there is also a sample.js file inside each part with a small sample dataset to test your implementation.
/src

|
-/Day1...
|
-/part1
-/part2
-input.js
-/Day2...
Just go over each puzzle and try to solve the problem using a test suite written in Jest.
Enjoy!!
