This demo shows a simple React component transpiled in the browser using the babel

settles on the array of arrays approach.

- `preact` using the react compatibility library

- `react-native` deployment for iOS and android

Run `make react` to run the browser demo for React, or run `make next` to run

#### Preact
|
||||
|

`preact-compat` is an easy-to-use compatibility layer that provides equivalents
|

for `React` and `ReactDOM`. The `preact` demo uses the same JSX component code!
|
||||
[The docs](https://npm.im/preact-compat#use-without-webpackbrowserify) explain
|

how to convert the in-browser React demo to Preact.

#### Server-Rendered React Components with Next.js
