This demo shows a simple JSX component transpiled in the browser using the babel
This demo shows a simple React component transpiled in the browser using the babel
standalone library. Since there is no standard React table model, this demo
settles on the array of arrays approach.
Other scripts in this demo show:
- server-rendered React component (with `next.js`)
- `preact` using the react compatibility library
- `react-native` deployment for iOS and android
## How to run
Run `make react` to run the browser demo for React, or run `make next` to run
the server-rendered demo using `next.js`.
## Internal State
The simplest state representation is an array of arrays. To avoid having the

To run the React Native demo, run either `make ios` or `make android` while

## Other Demos
#### 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
The demo uses the same component code as the in-browser version, but the build
