## What it is
Jakt is a memory-safe systems programming language developed by the SerenityOS project, featuring automatic reference counting, strong typing, and bounds checking. It currently works by transpiling to C++ and is under heavy development.

## Use cases
- write memory-safe systems code without a garbage collector
- learn how a programming language compiler is built
- contribute to SerenityOS tooling
- transpile a safe language to C++
- experiment with reference-counted pointer types

## When to choose
- you want a memory-safe systems language with ARC semantics
- you're contributing to SerenityOS or its ecosystem
- you want to study or hack on a compiler written in C++

## When to avoid
- you need a stable, production-ready language
- you need a mature ecosystem of libraries and tooling
- you can't rely on clang for the C++ transpilation step

## Facets
- artifact type: library
- maturity: experimental
- function: compiler, programming-language
- domain: programming-languages, compilers, developer-tools
- platform: windows, cpp
- tags: memory-safety, transpiler, systems-programming, serenityos, linux, macos
