## What it is
IoT.js is a lightweight JavaScript platform for Internet of Things devices, built on the JerryScript engine and written in C. It provides a Node.js-like API for resource-constrained hardware such as Raspberry Pi and STM32 microcontrollers.

## Use cases
- run javascript on embedded iot devices
- script a raspberry pi or stm32 with javascript
- build low-memory iot applications
- prototype iot device logic in js
- run a javascript REPL on a microcontroller

## When to choose
- you need JavaScript on memory-constrained IoT hardware
- you want a Node-like API on embedded Linux or MCU targets
- you're targeting Raspberry Pi or STM32 with minimal footprint

## When to avoid
- you need an actively maintained runtime
- you're building general-purpose server or web applications
- you need full Node.js compatibility or modern JS features

## Facets
- artifact type: framework
- maturity: abandoned
- function: interpreter, embedded
- domain: iot, embedded-systems
- platform: embedded, iot, cross-platform
- tags: javascript-runtime, jerryscript, samsung, microcontroller, raspberry-pi, low-memory, javascript, linux
