Clean code is highly preferable in terms of quality and maintenance. Why is this the case, and how can you benefit from it?
Contrary to what you might think, the term 'clean code' is not only up the developer's alley. It can be incredibly useful to you, too. Let's consider the opposite for a moment: badly written code can cause lots of problems, especially in the long run. At some point, it will be impossible to maintain, and you will have to write new code, which will take time and money. In the words of Robert C. Martin: "Of course, bad code can be cleaned up. But it's very expensive."
Clean code, on the other hand, is better in terms of quality and maintenance, and it's written in such a way that your future self and co-workers will understand it. Sounds good, doesn't it? Let's discuss in more detail how you can benefit from clean code.
Solving bugs and other issues, 'clean-code style'
First things first: initially, you will need to invest some time and money in clean code. The good news is, it will pay off. For example, maintenance will be much more efficient, and you'll be able to add new features in a breeze. Also, if you encounter a bug, you can solve it 'clean-code style.' What this means? Well, at first, it will take a bit more time. But since a bug will never occur again after you've solved it, you'll save a ton of time and money in the long run. Think of the project managers, QA people, and developers who will no longer have to rack their brains over recurring bugs. They can be more productive and efficient in other areas.
Enhancing quality: the snowball effect
Finally, let's talk quality – clean code gets the snowball rolling. Solidly written code results in a better product and, therefore, satisfied customers. As we all know, a loyal clientele is the best foundation for growth. A thriving company, in turn, will make for motivated employees in general and motivated developers in particular. That's where we get to the core of the process: an inspired developer will create even better – or, cleaner – code. And that's how quality will continue to increase over time – in all corners of your business!
In that light, we'd like to share a quote from Martin Fowler that illustrates why clean code is worth the investment: "Any fool can write code that a computer can understand. Good programmers write code that humans can understand."
