After years of starting, killing, restarting, and refining, I finally realised a dream: operating JavaScript at the low level. And I'm giving it to the world!

Script compiles JavaScript and TypeScript to native machine code, without garbage collection, featuring:

• Rust-inspired ownership & borrow checking
• Native compilation via LLVM & Cranelift
• Full TypeScript syntax with type inference
• Zero-overhead abstractions & standalone binaries

It compiles down to SSA-based IR and produces self-contained executables that run with native performance. As a result, we finally have a language that writes like JS but runs like Rust!

This week marks a major milestone for Script: we've officially begun Phase 4 - Self-Hosting Compiler. After completing Phase 3 (Language Completion), we're now taking the next step toward making Script a truly self-contained language that can compile itself. This post explores what self-hosting means, why it matters, and how we're building toward it.

This week, we added 10 standard library modules to Script in just 7 days. From path to math, from date to fs, we went from a minimal runtime to a production-ready standard library. This post shares the lessons we learned, the patterns we established, and the decisions we made along the way.

Script now has full async/await support, built on top of Tokio—Rust's production-grade async runtime. This post dives into how we implemented Promises, the await opcode, and bridged Rust's async world with Script's VM.

Script now has full ES module support with import and export statements, file-based resolution, SHA256 caching, and cross-module function calls. This post explains how we built it, the decisions we made, and what's coming next.
