hexagony VS advent-of-code

It's got a larger symbol set, but it's still relatively code-like. If you want some obtuseness, try out Hexagony where you code in a hexagonal grid, using a hexagonal memory, or Malbolge, who's entire goal is to be as hard to code in as possible.

Some examples that I find interesting: * Brainfuck * Marbelous * Hexagony * Emoji

The most highly upvoted solution to this problem is a 6-character-long program written in the Hexagony programming language.

(As an aside, some people "stop" here and then make programming languages based on this - because that is a simple interpreter... you could write a compiler for this language, or extend it - and the great golfing languages take that starting spot and keep going - don't worry about trying to replicate it, it takes some insanity to go that far - the point is that a stack based language is the starting spot for some impressive systems... like the JVM itself)

How about a programming language?

JavaScript

Almost walked away from this when caught out by the "empty" space flipping. But stuck with it and managed to make it work without changing my approach too much.

I enjoyed this one, despite all the reading. Felt like a nice change of gear from yesterday's. Using recursion to read sub-packets from the binary string, using a function that returns the value (or version sum in part 1) as well as the length, so I know where to read from for the next sub-packet.

Enjoyed today's one, short and sweet

Mine is similar (but in JS)

Struggled to get my head around the explanation of part 2 today, need more coffee

not the most inspired solution

JS solutions, already settled back into the habit of relying on reduce functions
