How to use

1. Stick to the days\<day#>\<part#>.js structure
2. Create your input file (no extension) in the day directory
3. Write this in your terminal to start

$ npm run start day# part#

For day 1 / part 1 that would be npm run start 1 1

input data

To get the input data in your code you can use the global inputFile function

const data = inputFile();

This will return an array of the input data split by newline. If you want more control you can do that in multiple ways

// Split by ":"
const data = inputFile('input', ':');

// Don't split, return as String
const data = inputFile('input', false);

// If file name is different than "input"
const data = inputFile('input2');

services

All service files are injected globally as the name the function is exported as.

// services/addOne.js
export function addOne() { ... }

// This would be globally available in your code as "addOne"
