It also helps developers to find the hidden bugs and vulnerabilities in the system. 1) Code refactoring: It often referred to simply as refactoring. It is widely believed that refactoring improves software quality and developer productivity. But as beneficial as it is, it is equally hated by project owners who get convinced into refactoring by the developers, although the tangible effects of the process may only be felt by the development department. Often a good tactic when adding new features to old, poorly factored code is to refactor the target code then add the new feature. There are a variety of reasons for refactoring code including performance, readability, and future scalability. However, few empirical studies quantitatively assess refactoring benefits or investigate developers’ perception towards these benefits. I am suggesting that developers use code refactor tools because they has many benefits that go beyond the obvious, and is an activity worthy of the time devoted to it. Code refactoring is a very important weapon in programmers’ arsenal allowing them to combat technological debt. Well-structured code is also less error-prone when it comes to extending it. Benefits of Code Refactoring Seeing the Whole Picture. It may not make much sense when you hear that rewriting the already written code is cost-effective but hear us out. You do not need to worry about duplicate codes, as those are all commonified and in a single place. The code becomes more readable and easier to understand. Refactoring code does have merit on its own just in terms of code quality and correctness issues, but where refactoring pays off the most is in maintenance and evolution of the design of the software. If the method is redefined, refrain from this technique. In case of code refactorings, the improvement in structure is minimal — in case of design refactorings, it is more involved. Automatically. It is intended to change the implementation, definition, structure of code without changing functionality of software. In this sense, refactoring has been underutilized. Bad Smells in RPG Code The term bad smells comes from Refactoring - Improve the design of existing code and is a reference to one of the author's grandma's baby rearing skills - If it stinks, change it. It is widely believed that refactoring improves software quality and developer productivity. By minimizing the number of unneeded methods, you make the code more straightforward. What are the benefits of refactoring? Of course, this assumes the old code is not as good as it could be. Changing a local variable name or a static function name will not change the underlying code: the assembly produced will be identical. Automated code refactoring Refactoring improves the underlying structure. Refactoring is safest and cheapest when it is done in many small increments rather than in large batches. Helps in faster programming: All the above benefits leads to faster programming. Benefits. Make sure that the method isn’t redefined in subclasses.

Agile teams are maintaining and extending their code a lot from iteration to iteration, and without continuous refactoring, this is hard to do. Often it becomes easier to spot the bug location. “Refactoring is a controlled technique for improving the design of an existing code base. Rather, it is typically interwoven into architectural transformation projects as discussed in the Transformation section. Refactoring is rarely performed as a stand-alone activity. In the code refactoring process, you eliminate all the code smell problems. How to Refactor. Generally, software that’s been in service for a few years collects lots of changes due to bug fixes, optimizations and new features. So time is saved, while at the same time the quality of the code is enhanced. In short, the process of refactoring involves taking small, manageable steps that incrementally increase the cleanliness of code while still maintaining the functionality of the code. Delete the method. You tend to create a Class for each behavior separately helping you decouple code. Refactoring a project so that it reflects our current abilities and standards, not to mention industry standards, is a professional must.
