Advent of Code 2023

My solutions to Advent of Code 2023 🎄

Dependencies

Use yarn to install dependencies: yarn install.

As of writing, I'm using node 20 via nvm. If you have nvm installed, simply run nvm use and confirm with node -v

$ nvm use
Found '/Users/thaddeus/src/advent-of-code-2023/.nvmrc' with version <20>
Now using node v20.10.0 (npm v10.2.3)

$ node -v
v20.10.0

Running the code

Each day's source file includes a set of tests (.test.ts). These files load data from local definitions or separate files. They'll always demonstrate the correct answer to each day's puzzles, along with some extra tests to validate smaller parts of the solutions.

The package.json has a test script configured, so running yarn test is adequate to invoke jest and have test results displayed.

$ yarn test
yarn run v1.22.21
$ jest
 PASS  src/day-03.test.ts
 PASS  src/day-01.test.ts
 PASS  src/day-02.test.ts
