What is Refactoring?

Refactoring is the process of restructuring a code without changing or adding to its functionality and external behavior. There are a lot of ways to go about refactoring but it mostly goes towards applying standard basic actions. These changes in the existing code save the software’s functionality and behavior since the changes are so tiny, they are less likely to cause any errors. So, what is the point of refactoring? Well, refactoring is to turn any messy confusing code into a clean understandable one instead. When a code is messy it means that the code is hard to understand and maintain, when it’s time to add a required functionality it causes a lot of problems with the code because it’s confusing already. With a clean code, it’s easier to make any changes and improve on any problems. Also with a clean code anybody who ever works with the code is able to understand the code and can appreciate how organized it is. When a messy code isn’t cleaned up it can affect any feature developments because developers have to take more time to understand the code and track the code so that they can make any changes themselves.

Knowing when to refactor is important and there are different times to refactor your code. Like refactoring, while you’re reviewing the code, reviewing the code before it goes live is the best time to refactor and make any changes you can before pushing it through. You can also schedule certain parts of your day to refactor your code instead of doing it all at once. By cleaning your code you are able to catch any bugs before they create any problems in your code. The main thing about refactoring your code is that cleaning up a dirty code can reduce technical debt. Clean code is easier to read and if anybody else besides the developer works on that code they are also able to easily understand that code as well as maintain and add features to it. The less complicated the code is, it can lead to improved source-code maintenance. With a clean code, the design can be used as a tool for any other developers it can become the basis of a code elsewhere. This is why I believe that refactoring is important because changing just the smallest piece of code can lead to a better functional approach to programming. It helps developers get a better understanding of the code as well as making better design decisions.
