LLJS is a typed dialect of JavaScript with a C-like type system and manual memory management, compiled to plain JavaScript via the ljc compiler. It is an early research prototype exploring statically typed, low-level features in a dynamically typed language.

Use cases

• write memory-efficient javascript with c-like types
• compile typed javascript to plain javascript
• avoid garbage collector pauses in hot javascript code
• detect memory leaks and double frees in javascript
• experiment with low-level typed programming in javascript

When to choose

• you need manual memory control and typed memory buffers in javascript
• you are researching low-level typing in dynamic languages
• you want a C-like memory model that still runs in JS engines

When to avoid

• you need a maintained or production-ready tool
• you want modern typed JavaScript - use TypeScript instead
• you need WebAssembly-level performance - use wasm
