When Should You Comment Your Code

Should You Comment Your Code Examples Warning readers away from your code is like turning on your car's hazard lights: an admission that you're doing something you know is illegal. instead, rewrite the code to something you understand well enough to explain or, better yet, that is straightforward. Whether you're a beginner just starting your coding journey or looking to improve your commenting practices, this comprehensive guide will teach you how to write professional, readable, and scientifically backed comments that make your code easier to understand and maintain.

How Much Should You Comment Your Code Segue Technologies Discover the top 10 code commenting practices for developers to enhance readability and maintainability of codebases for better collaboration and success. Good comments should illuminate code's purpose and behavior, using clear and precise language that helps developers understand the code's intent, avoiding technical jargon or overly complex explanations that might further obscure the code's meaning. Ideally, your comments should describe your code at a meta level, indicating not what you're doing but why. also how, if you're doing something unusual or tricky. In this comprehensive guide, we’ll explore the art of commenting your code, discussing best practices, common pitfalls, and how to leverage comments to improve your overall coding skills.

In this comprehensive guide, we’ll explore the art of commenting your code, discussing best practices, common pitfalls, and how to leverage comments to improve your overall coding skills. Write clear code before adding comments. the most important concept here is that the code itself is the primary means of commenting and documentation. within 100 or 1000 lines of code, there is a wealth of opportunity to embed your intended meaning and use context to communicate with your audience. But you should comment the "why" when parts of code are about tricky edge cases or bugs and doesn't make sense at first glance. you should also comment when the code rely on a heuristic or an arbitrary choice where the intent is hard to reverse engineer. In general, you need to avoid over commenting: the cognitive overhead of reading obvious comments actually makes code harder to understand, not easier. developers waste mental energy parsing. Most developers will have heard somebody say “good code is self documenting”. but is it true? today we’re talking about when to comment code, and when to let it speak for itself.
