commenting code is bad

If you are building a library or framework that other developers will use, you need some form of API documentation.The further removed from the source code your API documentation is, the more likely it is to become outdated or inaccurate over time. Unfortunately, the comments don’t always follow the code or simply can’t follow the code.This results in comments that get separated from the original code they describe, which makes the comments less and less accurate.You could make the point that developers should be disciplined enough to maintain the comments and keep them accurate. I often see comments above variable or function names describing what the code does (or is supposed to do). If the code is already simple and obvious, there’s no need to add a comment.Still, there are times when no matter what you do to the code itself, a clarification comment is still warranted.Usually this happens when you need to add some context to a non-intuitive solution.There are also times when — after a lot of thought and experimentation — it turns out that the seemingly naive solution to a problem is actually the best. Tax Identification Number: 82-0779546) A good strategy to mitigate this is to embed the documentation directly into the code and then use a tool to extract it.Here’s an example of a documentation comment from a popular JavaScript library called If you write documentation comments you should ensure that they follow a consistent standard and that they are easily distinguishable from any inline clarification comments you may also want to add. These comments make it clear that the programmer was not able to think of an expressive enough name or that their function is doing more than one thing.Naming things in your code is extremely important. As Sammy Larbi said in Common Excuses Used To Comment Code, if your feel your code is too complex to understand without comments, your code is probably just bad. It is the only source of truly accurate information. Comments Let You Exhibit Without Getting in Your Way.
The good news is that most code editors support “code folding” which allows us to collapse the comments so we can focus on the code.Clarification comments are intended for anyone (including your future self) who may need to maintain, refactor, or extend your code.Often, a clarification comment is a code smell. Comments do not make up for bad code. Because that’s what comments are.

We also have If you are building a library or framework that other developers will use, you need some form of API documentation.The further removed from the source code your API documentation is, the more likely it is to become outdated or inaccurate over time. You should strive to remove clarification comments and simplify the code instead because, “good code is self-documenting.”Rather than decorating a slightly confusing statement with a clever rhyme — in Don’t get me wrong, there are times — especially when you are slogging through a crushing workload — where injecting a bit of humor can be good for the soul. freeCodeCamp is a donor-supported tax-exempt 501(c)(3) nonprofit organization (United States Federal But this truth has been so abused that most people who utter the phrase have no idea what it really means.In this article we’ll look at the good, the bad, and the ugly when it comes to commenting your code.For starters, there are really two different types of code comments. It’s easy to project your own worldview that code is a foreign language understood only by computers, and that you are doing the reader a service by explaining what each line does in some form of human language. I call them Documentation comments are intended for anyone who is likely to consume your source code, but not likely to read through it. Most coders would chuckle and move on, ignoring the code smell.There are also times when you come across a comment that is redundant. But you SHOULD leave a comment warning others not to pursue some seemingly obvious “better solution,” if you’ve already tried and rejected it. Even though there are some forms of good comments, I think that you should try to minimize the usage of comments in general.// Check to see if game is finished and player can not spawn again// Copyright (C) 2019 by Someone, Inc.
