Add section to explain importance and order of package.json

[AntonyFagundez]

Many libraries that supports many bundlers and type of apps like @mui. Not use the exports field.

They use a package.json inside of they components to specify, where is the module, the main, the types, etc. (module resolution)

It would be excellent if you can add a section for this, or I can make contribution with more info about that.

PD: Thanks for sharing this guide it's excellent.

Yup, that's likely because the exports field is fairly recent, and also adopting it is likely a breaking change.

Yeah, this is a common pattern for libraries that don't support package exports.

I could be wrong, but I don't think this is necessarily best practices for "modern" bundling, however. I'm under the impression that it's better to use package exports nowadays.

I am open to seeing if that's not necessarily the case, though.
