Additional articles seem to be important - renaming?

[Sammeeey]

When I started to study javascript.info it appeared to me as if the Part 3 (Additional articles) was just additional - hence not so important - information (because of its name).
Now I feel that the covered topics are important fundamentals (just a bit harder to be summarized under one main topic).

I suggest to rename Additional articles to something like Further important articles or Additional fundamental articles - something that makes clear that Part 3 isn't something to be skipped.

What do you think?

Many of the topics that are described in the Additional Articles section are really additional and not as important as, for example, the articles in the first part of the tutorial. For example, binary data - used in practice quite rarely.

The third part of the tutorial also contains sections whose understanding is not possible without knowledge from the first and second (predominantly) chapters. For example, Network requests, Storing data in the browser, Web components.

Also the chapter about regular expressions, it's unclear here why it's in the third section. Regular expressions are one of the most commonly used language features in practice.

My suggestion for the title of this chapter is "thematic sections".
