Is there any browser extension which identifies and shows which programming languages have been used to create a site?

I know we can see the code by going to page source or inspect but I'm asking from a begginers perspective who struggles to identify languages.

No. All websites are written using HTML, CSS and JavaScript simply because nothing else runs in the browser. But that is just the frontend part, the backend can be written in literally anything and there is usually no way to tell because it runs on the server and you can't see the source.
