## What it is
ElixirScript is a compiler that converts Elixir code into JavaScript by transforming the Elixir AST into a JavaScript ESTree AST. It integrates as a Mix compiler so Elixir modules can be compiled and run in the browser or Node.js.

## Use cases
- write frontend JavaScript code in Elixir
- compile Elixir modules to run in the browser
- use Elixir functional style for JavaScript projects
- interoperate Elixir code with JavaScript via FFI
- build web apps with Elixir instead of JavaScript
- test Elixir modules that call JavaScript APIs

## When to choose
- you know Elixir well and want to write browser code in it
- you want functional immutable patterns compiled to JavaScript
- you need an Elixir-to-JS pipeline integrated with Mix

## When to avoid
- you need an actively maintained tool - last release was 2019
- you want full Elixir standard library support in the browser
- you need production-grade frontend tooling today
- you prefer modern alternatives like Gleam or LiveView

## Facets
- artifact type: library
- maturity: abandoned
- function: compiler, build-tool, developer-tools
- domain: compilers, programming-languages, web-development, frontend
- platform: elixir, browser, cli
- tags: transpiler, elixir-to-javascript, estree, mix-compiler, ffi, functional-programming, nodejs
