# Fennel
[Fennel](https://fennel-lang.org/) is a programming language that brings together the speed, simplicity, and reach of [Lua](https://www.lua.org/) with the flexibility of a [lisp syntax and macro system](<https://en.wikipedia.org/wiki/Lisp_(programming_language)>).
Fennel code is compiled to Lua, which then runs in the browser using [Fengari](https://fengari.io/). See documentation for Lua language support in LiveCodes [here](./lua.html.md).
:::info Note
Lisp language family supported in LiveCodes includes [Common Lisp](./commonlisp.html.md), [Scheme](./scheme.html.md), [ClojureScript](./clojurescript.html.md) and [Fennel](./fennel.html.md).

## Usage
JavaScript interoperability and DOM access is achieved using [`"js"` module](https://github.com/fengari-lua/fengari-interop).
import LiveCodes from '../../src/components/LiveCodes.tsx';
This example demonstrates usage, JavaScript interoperability and DOM access:
