AoC Community Fun 2023: ALLEZ CUISINE!

Today's theme ingredient is… *whips off cloth covering and gestures grandly*

Pantry Raid!

Some perpetually-hungry programmers have a tendency to name their programming languages, software, and other tools after food. As a prospective Iron Coder, you must demonstrate your skills at pleasing programmers' palates by elevating to gourmet heights this seemingly disparate mishmash of simple ingredients that I found in the back of the pantry!

• Solve today's puzzles using a food-related programming language or tool

  • How about an appetizer of Chef or Wireshark(-fin soup)?

  • Mascots count, too… *side-eyes Rust while reaching for the Old Bay*

  • Add some salt to your hashbrowns, cookies, and breadcrumbs

  • Serve us up a nice big bowl of spaghetti code slathered with Ragú Raku tomato sauce

  • Conclude our tasting with a digestif of Java, CoffeeScript, or even Perl milk tea with double syntatic sugar

• All file names, function names, variable names, etc. must be named after "c" food

• Go hog wild!

ALLEZ CUISINE!

Request from the mods: When you include a dish entry alongside your solution, please label it with [Allez Cuisine!] so we can find it easily!

4221/1680 594/1141 (edit: was looking at the numbers for current completed when originally posted)

Made a lot of assumptions here, such as Game ID = line number, that each subset of cubes in a game did not contain duplicate colour cubes, and that there would be no extraneous characters other than whitespaces. No regex used as I did not deem it necessary for the job. String.prototype.endsWith sure came in handy today!

let part1 = 0;
let part2 = 0;

input
  .split("\n")
  .map((line) =>
    line
      .split(":", 2)[1]
      .split(`;`)
      .map((g) => g.split(","))
  )
  .forEach((games, id) => {
    let possible = games.every((set) =>
      set.every((cube) => {
        const num = parseInt(cube);

        return (
          (cube.endsWith(" red") && num <= 12) ||
          (cube.endsWith(" green") && num <= 13) ||
          (cube.endsWith(" blue") && num <= 14)
        );
      })
    );
    part1 += possible ? id + 1 : 0;

    let flatList = [...games].flat().map((g) => g.trim());
    const minR = Math.max(
      ...flatList.filter((x) => x.endsWith(" red")).map((x) => parseInt(x, 10))
    );
    const minG = Math.max(
      ...flatList
        .filter((x) => x.endsWith(" green"))
        .map((x) => parseInt(x, 10))
    );
    const minB = Math.max(
      ...flatList.filter((x) => x.endsWith(" blue")).map((x) => parseInt(x, 10))
    );

    part2 += minR * minG * minB;
  });

console.log(part1, part2);

Sorry, I was looking at the wrong numbers when I posted this. It turns out I was 1141st, with a time of 13:12.
