## What it is
Nerd (formerly NectarJS) is a JavaScript native compiler that compiles JS and NerdLang (a JS subset focused on efficiency) directly to native binaries with no VM, bytecode, or garbage collector. It targets many platforms including Windows, Mac, Linux, iOS, Android, Raspberry Pi, and STM32/Arduino.

## Use cases
- compile javascript to a native executable
- run js on microcontrollers like arduino or stm32
- build small standalone binaries without nodejs runtime
- compile javascript for embedded devices
- avoid vm and garbage collector overhead in js apps
- cross-compile js apps for windows mac linux android ios

## When to choose
- you need small, fast native binaries from JavaScript source
- you target embedded or resource-constrained hardware
- you want no runtime VM or GC dependency

## When to avoid
- you need full modern EcmaScript compatibility (only ES3 targeted so far)
- you rely on the Node.js/NPM ecosystem at runtime
- you need a mature, actively maintained toolchain for production

## Facets
- artifact type: cli-tool
- maturity: experimental
- function: compiler, programming-language, developer-tools
- domain: programming-languages, compilers, developer-tools, cross-platform
- platform: windows, cross-platform, cli, wasm
