Universal WebAssembly Compiler

Multi-Language Support

TypeScript, JavaScript, Rust, C-like, Python-like syntax - all compile to WASM.

Full Compiler Pipeline

Lexer → Parser → Type Checker → IR → Optimizer → WAT → WASM binary.

Advanced Optimizations

Constant folding, dead code elimination, strength reduction, peephole opts.

Rich Type System

Generics, unions, tuples, pointers, references, optionals, and more.
