[Discussion] Consider ESM-only for v5?

[jcbhmr]

Popular opensource guru sindresorhus has done this https://github.com/sindresorhus/meta/discussions/15 https://gist.github.com/sindresorhus/a39789f98801d908bbc7ff3ecc99d99c

I think that this is a good step to avoid the dual package hazard: #37

@mesqueeb I've been working on various things all-at-once in the https://github.com/mesqueeb/is-what/tree/jcbhmr branch. Just thought I'd let you know. 😊 I hope to be able to break that branch into multiple "feature-ish" PRs to be considered somewhat independently.

https://github.com/mesqueeb/is-what/tree/jcbhmr does these things:

1. [x] Split index.ts into multiple files
2. [x] Add a bunch of documentation for some of the functions (still have more to do)
3. [x] Remove useless "isMap() detects if the value is a Map" comments
4. [x] Remove redundant JSDoc @param declarations (already typed by TS)
5. [x] Remove dist/ from source control
6. [x] Automate deployments to https://deno.land/x/is_what via tags on a separate build branch #53
7. [x] Improve separation of concerns with publishing workflows #40
8. [x] Add a docs preview action to give a .zip of what would be deployed
9. [x] Add more tests (a LOT more tests)
10. [x] OPINION/OPTIONAL: Reset to default Prettier configuration. Defaults are good. I like defaults.
11. [x] Put prettier in package.json (before I eventually removed it and used the defaults)
12. [x] Add a JSDoc prettier plugin #45
13. [x] Add a JSDoc package.json plugin #45
14. [x] Add TSX as a dev dep #44
15. [x] Use node --test and node:test for test running #44
16. [x] Add a prettier pre-format hook
17. [x] DISCOURAGE local npm publish by removing the np helper #40
18. [x] Use plain tsc instead of rollup #44
19. [x] ONLY provide .js (no .cjs) for ESM-only package #47 #37
20. [x] Revamp readme to shift docs to the docs website (it's shorter)
21. [x] Improve readme with images
22. [x] Remove .github/FUNDING.yml with the expectation that it will be moved to mesqueeb/.github

any probably more stuff to come! Bear in mind that this https://github.com/mesqueeb/is-what/tree/jcbhmr WILL NOT BE MERGED INTO MAIN but instead is my "playground" 🪀 that I want to show off and get feedback on 😊

Don't run too fast because it'll be harder to communicate about how we feel about each change 😅
