Non-explanatory docs for: https and http2

[akopchinskiy]

Docs don't explain what's the difference between these two modules.
Is http2 is a superset of http and https? Does http2 use TLS/SSL for encryption?
Do I need to choose between http2 and https? Or I can simply use http2 because it newer and cooler? :)
There's absolutely no info for that.

They're API reference documentation, not primers on internet protocols. I don't think what you're asking for belongs there.

Yes, if you're looking for an article introducing difference of them, you can just go to Wikipedia

close as resolved

@bnoordhuis And I'm asking about API documentation. The question was clear:

Do I need to choose between http2 and https? Or I can simply use http2

@himself65 What does this have to do with Wikipedia? (btw, It's doesn't give answers to my questions and you didn't read it, whatever)
I asked about API and it's composition.
