I don't really agree.
Let's take a B4X project for example. Should I read ALL the documentation to fix a bug? Lots of topics that have nothing to do with it?
No, I read any error message or the line that triggered it. Then I could possibly read the documentation, but often it is not necessary, it is sufficient to search on the site.
Today you can even ask ChatGPT what the error could be.
In short, it is not true that it is more important and simpler to read the documentation, it is better to carry out well-done debugging (unless you do not know at all the language you are using; in this case it is better for you to go fishing
)
