"Web runs on browsers" yes but that's a client, doesn't really have anything to do with not learning Javascript over Python but instead learning it alongside it. Browsers don't care about your backend implementations hence the use of frameworks like Django and Flask. You can run React and Django simultaneously so you don't necessarily need to pick one or the other. I always encourage people to learn using their favorite languages first. Language and frameworks are just tools, you pick the best tool to complete a job and on to the next, no need to revolve our personalities around them.

True. That's what the last line says.
Treat languages like crushes not life partners.
