fast_brainfuck.lua
High performance brainfuck transpiler/interpreter for Lua with FFI support. Very fast implementation with multiple optimization passes.

WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
I wrote my own Brainfuck to LuaJIT transpiler https://github.com/ExtReMLapin/fast_brainfuck.lua It beats any other available interpreter/transpiler in others scripting languages
I think writing a brainfuck JIT is a great hobby project for learning x86 assembly and the basics of how jit compilation of bytecode works. I also wrote an x64 jit for brainfuck in c++ ( https://github.com/ccapitalK/bf_jit ) , it's surprising how similar it ended up being architectured to the code written in part 2 of this post. It's moderately fast (runs mandelbrot in about 1.1 seconds, and runs towers of hanoi in about 0.2 seconds).
Should compare it to the Mandelbrot set running under VeMIPS.
