How do I debug code?

• 0
  Hello!
  I'm a relative newbie, when writing code, all debugging boils down to printing the result of a function to the console and comparing it (IN A HEAD) with the expected result
  And something tells me that there are more civilized ways))
  Please advise any articles on this topic.
  And I really want to know, when it comes to adults, smart and experienced programmers, do they generally output to the console for such purposes?
