## What it is
A transpiler that converts JavaScript/TypeScript source code into readable C89 code. It was created to let developers program low-power IoT microcontrollers and wearables in JavaScript without the overhead of an embedded JS interpreter.

## Use cases
- convert javascript code to c
- transpile typescript to c for embedded devices
- run js logic on microcontrollers without an interpreter
- port a small javascript library to c
- program esp32 or wearables using typescript
- generate readable c code from js snippets

## When to choose
- you need to run simple JS/TS logic on memory-constrained microcontrollers
- you want readable, minimal C output that maps closely to your source
- your code sticks to the supported ES3 subset (no floats, eval, Date, Math, prototypes)

## When to avoid
- you need modern JavaScript features like prototypes, eval, Date, or Math
- your code relies on floating-point or big numbers
- you need a production-grade, fully spec-compliant transpiler
