Advent of Code 2025 — Solutions (JavaScript)

This repository contains my solutions for Advent of Code 2025 implemented as ES modules.

Project: Solutions for days 1–12 (one file per day).

Requirements:

• Node.js 22+ (or any Node that supports ES modules and top-level await)

Run a single day

Place the puzzle input in the inputs/ directory (for example inputs/day1.txt). Run a solution with:

./day1.mjs

Replace day1.mjs with the day you want to run.

Run all days (simple loop)

for d in {1..9}; do "./day${d}.mjs"; done

File structure

• day1.mjs — Day 1 solution
• day2.mjs — Day 2 solution
• day3.mjs - Day 3 solution
• day4.mjs - Day 4 solution
• day5.mjs - Day 5 solution
• day6.mjs - Day 6 solution
• day7.mjs - Day 7 solution
• day8.mjs - Day 8 solution
• day9.mjs - Day 9 solution
• day10.mjs - Day 10 solution
• day11.mjs - Day 11 solution
• day12.mjs - Day 12 solution
• inputs/ — puzzle input files (e.g., inputs/day1.txt)

Add a new day

1. Add day10.mjs implementing the solution (see previous days for basic setup)
2. Add the corresponding input file at inputs/day10.txt.
3. Run with chmod +x day10.mjs.
4. Run with ./day10.mjs or node day10.mjs.
