## Changes
- Updated dependencies
- Migrated to typescript
- Removed `div` in favour of Fragment
- Replaces `var` with `let` since we don't need global hoisting here
## Documentation / Examples
- [x] Make sure the linting passes by running `pnpm lint`
- [x] The "examples guidelines" are followed from [our contributing
doc](https://github.com/vercel/next.js/blob/canary/contributing/examples/adding-examples.md)
Resolves: https://github.com/zeit/next.js/issues/12545
This PR adds an example which show how to bundle and use WebWorkers in a next.js app.
The issue mentions Typescript, but adding typescript to the example should be fairly simple by following the documentation and seems out of scope for a web-worker example.
