I love using @esm.sh for browser importmaps!

- Handles npm, jsr and GitHub registries
- Checks the User-Agent to serve the right ES version (es2022, etc) – no bloat!
- Supports tree-shaking, so you can import just what you need

screenshot of a webpage that says "who up importing from jsr in the browser" and then demonstrates using @luca/flag, @std/cbor, @std/encoding, and @std/streams

chat i got jsr imports working 100% in the browser (no server side transforms like esm.sh, unless you import npm: specifiers, those are esm.sh)
