*PROJ in the browser*

Finally, after a long time and learning a lot in the process, I am getting a webpage that uses PROJ to perform coordinate transformations (similar to cs2cs)

https://jjimenezshaw.github.io/wasm-proj/transform.html

Best features:
- fast!
- it uses grid files when needed, downloading only the needed part of them.

There's another one that replicates projinfo:
https://jjimenezshaw.github.io/wasm-proj/projinfo.html

It has its js library behind it. I'm still developing it, improving it & adding more features.

Enjoy!
