Walt is a JavaScript-like alternative syntax for the WebAssembly text format that compiles .walt files directly to WebAssembly binaries. It lets front-end engineers write close-to-the-metal WebAssembly using typed JavaScript syntax without needing C, Rust, or LLVM toolchains.

Use cases

• write webassembly without learning c or rust
• compile javascript-like syntax to wasm binaries
• avoid llvm and binary toolkit dependencies
• integrate webassembly compilation into webpack builds
• edit wasm with javascript-familiar syntax
• generate webassembly modules in the browser

When to choose

• you want to write webassembly using javascript-like syntax
• you want zero-dependency wasm compilation in pure javascript
• you want to integrate wasm compilation into a webpack pipeline
• you find .wat text format too terse to work with directly

When to avoid

• you need a production-grade, stable toolchain
• you prefer compiling from c, c++, or rust with full ecosystem support
• you need the latest webassembly features and proposals
• you need long-term maintenance and active support
