Another time to think about refactoring is right after you’ve delivered a product to market. Understand the code. Both components and modules are intended to minimize reinventing the wheel. Look for more refactoring automation in other IDEs in the near future as refactoring shortcuts continue to be a major concern for the development community. Breaking down the refactoring process into manageable chunks and performing timely testing before moving on to other updates always results in a higher quality application and a better overall development experience. Refactoring improves non-functional attributes of the software. One example of abstraction is the Pull-Up/Push-Down method. Code refactoring is a process used in the DevOps software development approach that involves editing and cleaning up previously written software code without changing the function of the code at all. As the number of products using a module grows, the effort to promote it to a component becomes easily justified.

One of the smartest ways to approach it is to apply the Agile method and do it one step at a time, followed by testing. Enterprises have a lot of reasons for refactoring legacy code. This method involves creating new classes and moving functionality between old and new classes. This is done through various processes, including extraction and inline methods. By noticing that the code needs to be updated at that moment, the developer is doing his or her part to reduce future technical debt. By finding all calls to the method and replacing them with the content of the method, the method can then be deleted. For modules, changes are driven by the projects.
