The two drawbacks of module/nomodule that I don’t see being discussed often:
- babel compiles async/await down to regenerator when using modules: true (at least for now)
- the definition of “modern” browsers will change eventually and module/nomodule detection will not be relevant
Which is why I’d use ua sniffing: https://github.com/KidkArolis/jetpack/blob/master/docs/07-differential-serving.md https://github.com/KidkArolis/jetpack/blob/master/docs/07-di...
