This article mainly explains why code refactoring is important in software development. The explanation in this article is simple, clear and easy to learn and understand. Please follow the editor's train of thought. Let's study and learn why code refactoring is important in software development.

What is code refactoring?

That's what code refactoring is. We will update or improve the internal structure of the code before it becomes chaotic, and cause any problems in the future. We refactored the code without changing the external behavior or functionality of the application. You may have made minor changes to the source code, but keep in mind that the functionality remains the same.

Don't think of code refactoring as rewriting code. Rewriting the code changes the behavior of the code, but refactoring does not.

The main idea of code refactoring is to make inefficient and overly complex code more efficient, simpler, more concise, and easier to understand. Code refactoring makes the entire application more efficient, secure, fast, maintainable and extensible. It can also help developers find hidden errors and vulnerabilities in the system.

Why is code refactoring important in software development?

Take the kitchen in your home as an example. What will happen if you don't wash the dishes today and do the dishes tomorrow? It may not be a problem for you from morning to night, but the next day your kitchen will be a mess, and you may be at a loss to clean up the whole mess. A similar thing happens in software development, when you don't pay attention to your code and clean up the mess, while not building features one by one throughout the application. You might find out how messy the whole thing is when you get to the back.

In the software development approach, when a team is involved in developing some applications, the code is managed by many programmers. In order to implement some new features or extend the functionality of the code, each member needs to understand the code, which can be achieved if the code is clean, simple, and easy to understand. No one likes to deal with messy code that is not constantly updated or improved as the system grows.

Refactoring code is mandatory for the sake of the rest of the team. The refactored code eliminates all the complexity of the code, and the code becomes cleaner and easier to understand. Debugging becomes easier because of its small functionality and correct placement.

1. Keep the code simple

Code refactoring removes all concepts of code complexity and makes your code cleaner and easier to understand. You will remove redundant code, unnecessary variables, too many parameters, longer methods, longer classes, too many conditions or unnecessary loops, and so on. You removed all the clutter from the code and eliminated all defects to avoid real damage.

When your code is simpler, simpler, and easier to understand, it becomes easier to use. Similarly, it becomes easier to extend some functionality or debug code. Code refactoring also helps to understand some unfamiliar software. By refactoring the code, you can test your application and learn what each part of the program does and how to build the entire application. This helps to better understand the project.

two。 Improve the performance of the application

It runs faster and smoother without unnecessary classes, functions, variables, methods, or any other messy application. If the code has been refreshed or updated recently, the performance of the application will improve. Your application generates a quick response and users no longer complain about performance degradation. This can lead to a better customer experience.

3. Save time and money in the future

Clean and concise code takes less time to understand and implement new features. No developer likes to spend time or waste time understanding messy code. Unrefactored applications need more time to extend or upgrade. In addition, if the application is damaged due to some problem, the organization needs to spend money to solve the problem, and the budget will increase.

4. Your code is out of date

Usually in development, we use libraries or frameworks that need to be updated over time. When newer versions of these libraries or frameworks appear, programs written in older versions may not run, or some errors may occur. If your application uses libraries that are no longer maintained or even exist, it will cause a lot of problems in the application. Your application may stop responding, or you may find many errors. You need to keep your code up to date to prevent this problem.

5. Improve system design

Over time, as you improve your code and understand your project in a better way, you will learn something new. You have implemented some functionality, and after a few months, if you only pay attention to your own code, you will find that it can be easier and easier to write. The solution you implemented a few months ago is not working well today. The overall design of the application can be improved by following some good practices and refactoring the code.

Poorly designed software may be good in the short term, but it will cause a lot of problems in the long run. To avoid problems in the future, it's best to spend some time refactoring your code and following good practices, rather than taking shortcuts and making quick and cheap choices.

Conclusion

Code refactoring is not just about improving code. This is a healthy habit for any company and should avoid any major problems or errors in the application. If it is updated or refactored regularly, the life of the project will be extended by several years. Your application runs faster and provides a better customer experience, which is critical to running any type of business. Instead of creating a big problem for yourself in the future, spend time in the code refactoring process when building your application.
