How does Reading Mode work in Safari and Firefox browsers?

Question

linux

Hello. Can you tell me, please, where can I read something about this topic? Or can anyone clarify this?
How do these browsers determine the usefulness of information for the user and display only what is needed (the title of the article and its text), isolate them from a common set of tags? Perhaps there are ready-made algorithms that work in a similar way?

Answer 1

make just compiles to an executable file.
