What is a hash? Query parameters?

No. String after #. For example:

https://example.com/action?param=value#hello

"hello" is hash

I think we should name it #

In RFC 3896 this part of URL is called "fragment identifier" or just "fragment". But "hash" is a popular term for call it. For example, property window.location.hash in JS.

I'd leave it as "hash". It's a common name.
