Answer 1

These topics are not covered by Sololearn courses. You will need to search the internet to learn more.

One good place to start, would be the website of these particular frameworks, because usually they do have detailed documentation, as well as "Getting started" guides and tutorials, to give you a hands-on experience how to use them.
Other than that, you can probably find plenty of tutorials on various blogs or on YouTube.. I cannot recommend any specific one though.

Answer 2

Mahdi Yaakub years ago there was a "Lesson Factory" feature in the app, which allowed normal users to create these bite-sized community lessons, which were then edited together by Sololearn team. They are more or less coherent, definitely not a fully well designed educational material... But then again, all the Sololearn courses are quite superficial anyway and only able to give you a glimpse into the basics. To get the full picture, the documentation of the language (or framework) is often the trivial best source.
