## What it is
ThinScript is an experimental programming language with TypeScript-inspired syntax that compiles to JavaScript, WebAssembly, and C. Its bootstrapped compiler is written in itself, and the project is explicitly an experiment not intended for real use.

## Use cases
- experiment with a TypeScript-like language compiling to WebAssembly
- study how a bootstrapped compiler works
- compile the same source to JavaScript, WebAssembly, and C
- learn compiler design by reading a small self-hosting compiler
- try an online compiler demo in the browser

## When to choose
- you want a small, readable self-hosted compiler to study
- you're experimenting with early WebAssembly tooling
- you want one language targeting JS, WASM, and C

## When to avoid
- you need a production-ready language
- you need garbage collection or memory safety
- you need a maintained toolchain or up-to-date WebAssembly support

## Facets
- artifact type: learning-resource
- maturity: abandoned
- function: compiler, programming-language
- domain: programming-languages, compilers
- platform: wasm, cpp
- tags: typescript-inspired, bootstrapped-compiler, wasm, transpiler, experimental-language, web, nodejs
