advent VS advent

My solution runs both parts in 3.5 ms on my 1.80 GHz Dell machine, which I think is pretty good for JavaScript. I explain my solution in the comments.

Here is a link to the Node module that handles my input fetching. The function that performs the actual request is below, using Node's built-in https module:

I made one in JavaScript as part of my AoC framework; feel free to steal the code.

JavaScript

I mean, yeah, others are welcome to use it: https://github.com/rjwut/advent

My repo is at https://github.com/rjwut/advent. It has all solutions for all years in Node, and includes auto input download, skeleton solution generation, and even OCR for the ASCII letters used in some puzzles.

I just earned my last missing star. (No surprise, it was 2019 day 22. 🤮) My repo has all solutions in JavaScript, the vast majority of which complete sub-second. I also wanted to make it more useful for people learning the language, so I tried to write things in a way that would be more easily readable and maintainable than your typical quick-and-dirty solutions, and there's lots of documentation, probably more than I'd normally write. I also included my framework for generating skeleton solution files and retrieving input from the site (throttled and cached, of course). It even includes my OCR module for reading the large ASCII art letters used in some puzzles. Hope somebody out there finds it helpful in their own quest to improve their coding!

Nice. I did that but traversing all directions in each inner loop iteration: https://github.com/tsenart/advent/blob/master/2022/8/one.go
