About:
JerryScript is a complete JavaScript engine specifically designed for resource-constrained devices like microcontrollers. It features a memory footprint of under 200KB and supports the ECMAScript 5.1 standard. This enables developers to run JavaScript code directly on IoT hardware with limited RAM and storage.

Key Features:

Ultra-low memory footprint (< 200KB RAM)
ECMAScript 5.1 compliant
On-device compilation and execution
C API for native bindings

Use Cases:

IoT device firmware development
Embedded systems scripting
Smart home device automation

Alternatives:

quickjs – QuickJS is more feature-complete but has a larger footprint
node – Node.js is for desktop/servers, not suitable for embedded devices
