Advent of Code 2023

This repository contains solutions for the Advent of Code 2023 as a daily practice to learn JavaScript and its ecosystem (node.js, npm, eslint) while testing github Copilot for the first time.

Comparison to Python

• Value (Python) vs reference (JS) equality tests
• No builtin support for doc strings in JS
• Lack of builtin functionality such as range, or set operations like difference, intersection in JS
• Inheritance via classes (Python) vs prototypes (JS)
• Seeminlgy error prone implicit type conversions in JS:

  1 + 2 + " foo" // => "3 foo"
  1 + (2 + " foo") // => "12 foo"
  1 + {} // => "1[object Object]"

• undefined everywhere instead raising proper exceptions in JS (e.g. access to non existing property)
• missing type hints in JS (though available in TypeScript)
• convenient getter syntax in JS via get instead of using @property in Python
