Imagine a messy room with clothes, books, and other items scattered everywhere. Finding something in that room would be tough, right? Now, think about writing messy code – it’s just as confusing, if not more! On the other hand, clean code is like an ...

Writing clean code is crucial for maintaining readable, organized, and efficient software. This post provides 10 practical tips for achieving cleaner code, such as using meaningful names, following the Single Responsibility Principle, avoiding unnecessary comments, making code readable, and using unit tests. It also covers the importance of managing dependencies, organizing project structure, using consistent formatting, avoiding hardcoding values, and limiting function length. By adopting these practices, developers can create more reliable and maintainable software.

How to Write Clean Code – Tips for Developers with Examples

Great post worth reading for me. As a beginner developer I always think that my code can be cleaner.

As a software developer i know how it is important … when i read someone code who don’t follow SOLID approach , it is very painful to read them

Lots of articles like this floating about and it’s fairly on par with the usual things said. It’s clean and well written, and I love that it has examples.
For anyone coming into the industry, use the tips not as “rules” but “guidelines”. Also expect a lot of the recommendations to be crushed in mature codebases - things let real messy, real fast.
I’ll call out a couple of things:
<ol>
<li>
Single Responsibility Principle and limiting function length are good guides, but too many people are dogmatic about them. Approach them pragmatically and think about what makes sense in terms of overall application complexity and readability. You don’t always need to adhere to SRP, and longer can be more readable then multiple smaller functions that are called out to.
</li>
<li>
Code comments. I will die on the hill of “write MORE code comments”. AND maintain them. Professional programmers are in the business of communicating with other people (through code). You don’t write code for a compiler - you write it for fellow developers. Comments are golden nuggets for future programmers. And if I hear one more person talk about “self documenting code”… 😠
Is writing good comments hard? Yes. But no harder than anything else we have to do as developers if we want to do our jobs well. If you don’t like hard or effort then I suggest a different career.
</li>
<li>
Unit tests are good, but in your average business setting, damn are they hard to do and maintain (assuming you have time for them). What I wish I would see developers do is more manual testing as they develop. That also requires you to better understand the larger product and domain. Don’t be shy to test it end-to-end.
</li>
</ol>
Overall, thumbs up to this article.
