## What it is
The Toit language implementation, consisting of a compiler, virtual machine, and standard libraries for running a modern high-level language on microcontrollers, primarily the ESP32. It pairs with the Jaguar tool for live reloading of device applications over WiFi.

## Use cases
- program esp32 microcontrollers in a high-level language
- build iot device applications without writing c
- hot reload code on a microcontroller over wifi
- write i2c device drivers for embedded hardware
- run a garbage-collected language on constrained devices

## When to choose
- you want fast, safe high-level development for esp32 or similar mcus
- you need quick iteration cycles with live reloading on embedded hardware
- you prefer indentation-based modern syntax over c/c++ for firmware

## When to avoid
- you target microcontrollers other than esp32 without porting effort
- you need bare-metal control, tiny binaries, or cycle-accurate timing
- your project requires a large established ecosystem and community

## Facets
- artifact type: library
- maturity: active
- function: compiler, interpreter, programming-language, embedded
- domain: programming-languages, iot, embedded-systems, compilers
- platform: embedded, iot, windows, cpp
- tags: toit-language, virtual-machine, esp32, microcontroller, live-reloading, sdk, standard-library, linux, macos
