However 10 years later, it is also likely you&#x27;ll be reading the comments for the explanation and realise that what the comments say is different from what the code does (because over the span of 10 years the code was updated but not the comments) and that&#x27;s just as confusing.<p>If the code is written with meaningful variable and function names, and functions no larger than a screen, then lack of comments isn&#x27;t really a problem.
