I wrote a [script](https://github.com/j0lv3r4/dependency-version-updater) to update dependencies recursively in `package.json` files, e.g.:
```
$ node index.js --path="./examples" --dependencies="react=^16.7.0,react-dom=^16.7.0"
```
This PR contains the result against the examples folder.
- Looks like no other example provides a link to a hosted demo
- There is the "Deploy to now" badge, so it can be deployed on demand when needed
- The link is broken anyway
- Probably any example hosted by an individual contributor sooner or later will be cleaned up, doesn't feel like a reliable way to provide a live demo
