Learn Effect
Effect gives TypeScript the structure that makes AI-written code hold up, in a narrated, animated-code course where you watch the code build itself and hear why each move earns its place.
Coming soon
Learn Rust for TypeScript Developers
Read, review and steer the Rust your AI writes. Rust explained through the TypeScript you already know, with the tools and crates that matter.
What you'll learn
- Ownership and borrowing, the one idea TypeScript doesn't have
- Result and Option: errors without exceptions
- Traits, async with Tokio, Cargo and the crates everyone uses
- Rust in WebAssembly and native Node modules
