I've attempted to convert this to JavaScript:

https://url.spec.whatwg.org/reference-implementation/uri-validate.js

I've built a web page that makes use of it:

https://url.spec.whatwg.org/reference-implementation/uri-validate.html

Issues I encountered the process:

1) file_auth_path is defined with four instead of three double quotes

2) the last re.match rejects inputs that do not have a hash sign

3) extra, and potentially misleading, output is provided if instr starts 
with the characters "absolute:".
