Show HN: Brainfuck interpreter using TypeScript types (opens in new tab)

Yesterday, I made a Brainfuck interpreter using TypeScript types in ~40 lines of code for fun, because why not. Here's the file to look at: https://github.com/QuiiBz/tsfuck/blob/main/tsfuck.ts

It supports all brainfucks commands, but might not cover some edge cases/have bugs.

Have you ever made something similar using TypeScript type system?
