Advent of Code 🎄

Scaffolding for solving the Advent of Code (AoC) problems in JavaScript

Writing a Solution

To write a solution for a specific problem, navigate to the .js file for the solution. For example, the solution to part 01 published on day 01 of 2019 can be found at ./2019/day01/part01.js.

A stubbed method called solve has been provided for each solution that is already set up to receive the input data for that day from the input.txt in the same directory as an array of strings, one for each line in the input file.

Please note that the scaffolding will assume there is a new line at the end of the input file.

Tips for Success

• Update input.txt locally to try out different, smaller datasets as you work before tackling the large dataset provided by AoC
• Do all your work in the provided file, but don't try to fit it all into the solve method; using best coding practices and split out logical chunks into smaller methods
• Don't reinvent the wheel: the hardest part of these problems is the math, so do the hard work early by figuring out the best mathematical solution before turning it into code
• Use lodash, it's imported into every file already
• If lots of problems use some shared logic, consider moving that logic to a separate file in a shared folder (see 2019/shared/intcode.js)

Testing a Solution

To test a specific problem, run the following command:

# Command Usage
npm start <year> <day> <part>

# Command Example
npm start 2019 01 01

Archived Solutions

Please note that archived solutions are not updated as dependencies are updated, and testing an archived solution is not possible with npm start.
