Today we're talking about the Refactoring: Why and How. "Refactoring" involves reviewing and improving your code's structure and design without altering its functionality. It aims to make the code more readable, maintainable, and efficient. Properly executed refactoring can: - reduce the number of bugs - improve performance, and; - speed up development (more modular code makes it easier to add new features) Sometimes it's necessary to take a step back before we can go forward. If you never take time to remove redundancy, duplication, and inefficiency, adding new code will slow you down more than taking the time to optimize it. Here's a few tips on how to refactor like a pro: - Periodically review your code's structure, identify areas that need improvement, and decide on a plan to make the necessary changes. Keep note of these in a backlog, todo list, or nearby napkin. - Once you decide to refactor, create a backup of the original code and then make the changes incrementally. This way, you can test each change before moving onto the next one and minimize the risk of introducing new bugs. Removing bugs can sometimes create new bugs. - Watch for [code smells](=.Cv2EtZNVGqMN_5-L-4WTJyjv2947NUp2ZGYAyiLtpaE) , keep note, or fix them as they appear. These are not bugs, but instead are 'absolute violations of the fundamentals of developing software that decrease the quality of code'. It's better to deal with a bad smell before it's too late (this doubles as life advice). Remember, refactoring is an ongoing process that should be done regularly throughout the development lifecycle. As you gain experience, you'll develop an eye for spotting areas of improvement in your code. Keep in mind that the ultimate goal of refactoring is to improve the code's quality and make it easier to maintain and modify, which will save you time and effort in the long run.
