AssemblyScript is a compiler that translates a TypeScript-like language with WebAssembly types into lean WebAssembly modules, built on Binaryen. It integrates with the JavaScript/npm ecosystem so web developers can write WebAssembly without learning a new language.
Use cases
- compile typescript-like code to webassembly
- write wasm modules without learning rust or c
- build high-performance browser modules from javascript
- generate lean wasm binaries via npm
- access low-level webassembly memory and instructions from a familiar syntax
- add webassembly to an existing web project
When to choose
- you know TypeScript/JavaScript and want to target WebAssembly
- you want a lightweight npm-based toolchain with no heavy native dependencies
- you need low-level control over WebAssembly features and memory
When to avoid
- you need full TypeScript compatibility or dynamic JavaScript semantics
- you target platforms other than WebAssembly
- you require a mature GC-based language runtime with extensive libraries
