I was bored.I had a wild idea: why can't I vibe code an AOT compiler for TypeScript?However, the language is not strictly 1-1 typescript implementation; it's a subset with the features I want.This language was meant to write backend APIs and Microservices.I wanted to have 
- ARC Memory Management like Swift
- Multithreaded task-based async (Like C# or Tokio in Rust)
- Strictly Typed
- Decentralized Package management like Golang (Hate node_modules)
- Good std libraries like GolangI began using Inkwell LLVM since I was much better at reading Rust than C++. However, it wasn't that great, so I switched to LLVM's default C++.I got a basic web API running with SQLiteI gave the agent a VPS to benchmark against Node, Bun, Golang with zero optimizations.Benchmark: https://www.marina-lang.org/benchmark (I was expecting it to perform worse, but it did better) [Benchmark Before C++ Migration]Stack used
Model: GLM  5.3 Flash + Grok 4.7
Cost: ~$10Should I continue this project? Anyone interested? (Github: https://github.com/marina-lang-hq/marina)Examples at: https://github.com/marina-lang-hq/marina/tree/main/examplesPS: I haven't used C++ in production. Neither this is project is production ready. It's just a fun experiment.
