How do you use comments to improve the readability and quality of your code in open-source software?

If you are not using comments in your code, then what else you're doing? It is the most important thing in open-source codebases. ? They help developers, including those who did not write the code, to understand the purpose of specific sections, algorithms, or complex logic. ? Over time, code undergoes updates and bug fixes. Comments act as a guide for maintainers, making it easier for them to make changes without introducing errors. ? Comments can provide information about debugging. They might explain the expected behavior, assumptions made, or reasons behind a particular implementation.

Helps as a documentation, especially on fast paced and collaborative projects. Sometime the optimized solution results in lower readability, a good comment can be very helpful in such cases.

Using comments is essential when working with a larger codebase. Why are comments important? - Clarifying complex naming conventions: Sometimes, naming conventions in the code can be difficult to understand. Comments help clarify the purpose and functionality of the code. - Memory aid: Over time, we may forget the specifics of the code we wrote. Comments serve as a reminder of what each code block does. What to avoid when commenting: - Don't make obvious comments, - Avoid longer comments Best practices for commenting: - Keep it short and simple - Use simple technical vocabulary - Stick with "What is happening?"

Adding Comments in your code should be done only if extremely necessary. Comments are a good practice, but your code should ideally not require any comments. Commenting to convey the business logic, the reason which might not be clear firsthand should be written to write code needing fewer comments.

Les commentaires sont nécessaires mais ne le sont que lorsque l'on a besoin de préciser des éléments ne pouvant être explicité par notre code.

While adding comments make sure that the comments add value and don't duplicate information in the code. Also, regularly review and update comments to stay relevant with code changes. Here are few types of comments that we can add to our code:- ? Explanatory Comments: Clarify complex sections or algorithms with concise comments. ? TODO Comments: Highlight areas for future improvement or tasks with TODO comments. ? Function and Method Comments: Document input, output, and purpose of functions or methods. ? Code Block Comments: Provide context for logical sections or groups of code.

Some Do’s and Don’ts for commenting in your code ?? Stop making these mistakes ? Don’t include redundant or obvious comments that don't add value. ? Don't leave comments that are unclear or incomplete. ? Don't write comments only for yourself. Consider future developers who will read and maintain the code. ? Don't have inconsistent commenting styles. Adopt a consistent approach throughout the codebase. ? Instead: ? Provide a clear description of the purpose, parameters, and return values. ? Clarify the reasoning behind specific algorithms or approaches. ? Document temporary fixes or workarounds for known issues. ? Clarify the structure or format of the output data. ? Detail how errors are handled and why specific strategies are chosen.

Un exemple de commentaire, c'est spécifié, pour une fonction, les arguments passés en paramètres et le résultat qui est attendu. Mais pour l'intention de cette fonction, seul le nom de celle-ci doit l'expliciter afin d'éviter les évidences.

Les commentaires doivent expliquer l'intention et le contexte du code, pas sa mise en ?uvre. Incluez des informations pertinentes non évidentes, évitez les répétitions et les détails évidents. Identifiez les parties délicates ou complexes.

Commenting is necessary, and using a consistent commenting style can make a big difference. As I just know about JavaScript and Typescript. I will suggest you write documentation for functions using JSDocs. Here are some basics you should know about documenting functions with JSDocs: ? @param describes the parameters a function takes. ? @return describes the value a function returns. For example: /** * Add two numbers together. * @param {number} a - The first number to add. * @param {number} b - The second number to add. * @returns {number} - The sum of two numbers. */ function add(a, b) { return a + b; }

I would like to say that the method, in-line or block style commenting, is not as important as your adoption of ownership in the code overall. When you comment, and when you assume ownership of the code you are now going to write, refactor, or fix, you need to assume full ownership and remember to leave the code in a quality state for the next developer that may come behind you. Also, comments like unit tests need to weighed for coverage, not too much, not too little. I.e. you comment to provide quick indication of what you are doing. Seasoned developers can scan your code and very quickly understand your code, algorithms, or tasks. Simplicity is key but that's also for a discussion on refactoring.

La syntaxe et les styles de commentaire varient selon le langage, l'outil ou la convention utilisée. Les types courants incluent les commentaires d'une seule ligne, les commentaires multilignes, les commentaires en ligne et les docstrings, utilisés pour expliquer le code et générer de la documentation.

It is preferred to comment, the functions as soon as possible, this saves time and future usecases. As a developer, it helps in understanding my own code later on.

This is spot on. Comments are not for history. That's where SCM is king. I would also mention again that total ownership of the code is important. If you see historical comments, you can check Git e.g. and remove them. This is no different than seeing something else wrong with the code and fixing the problem. Be accountable. Own your work.

Il est crucial de commenter votre code lors de sa rédaction pour capturer vos pensées et intentions, mais aussi de les réviser régulièrement lors de modifications pour maintenir leur précision et cohérence.

Things to avoid to make sure your comments stay good! Quoting from the book Clean Code: 1. Any comment that forces you to look in another module for the meaning of that comment has failed to communicate to you and is not worth the bits it consumes 2. A long descriptive name is better than a long descriptive comment. 3. If the name requires a comment, it does not reveal its intent. 4. Don't comment on bad code -- ReWrite it! 5. Don’t Use a Comment When You Can Use a Function or a Variable

Comments are very helpful but also make sure not to be over-dependent on them. There should be a balance between code-readability and comments. Well written code still holds importance and makes refactoring process easier.
