JSON Import
strict mode is not automatic
- if you use type: module esm is enabbled (.js files are handled as .mjsthen - require will not be accepted anymore)
- hack: switch to type: module if possible: (this reduces bundle size by a lot)
```
  <script type="module" src="https://www.....js" async defer></script>
  <script nomodule src="https://www.....js" async defer></script>
```
- ...adapt webpack tooling to do 2 bundles to achieve that
how is everyone doing/dealing with these kind of breaking changes of ESM?
opinions on esbuild
- good to strip away the types of typescript and serve modules
- used by vite (esbuild is just super fast... but overpromises?)
