## What it is
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

## Facets
- artifact type: cli-tool
