This week I decided to write about refactoring code. I found a blog written by Charles Ouellet called “tips on Code Refactoring, from a Former Addict” this blog talks about his own experience on refactoring code. Refactoring is rewriting existing code and redoing it to make it more readable and more maintainable. When Charles first started he career as a developer he had a serious refactoring addiction where it even hindered his own work and delaying him from sending out his code to the consumer. For this blog, he talks about his own perspective of what are good reasons to refactor code and what are some bad reasons to refactor code.
Some of the good reasons to refactor code is to avoid technical debt. When you write code and the business takes off after it starts to grow even more there may be new problems that arise out of it. Refactoring code can be a cheaper option of fixing the program then to write a brand-new program to do the same thing that you want it to do. Another reason why it is good to refactor code is that it can be able to teach new people that are joining the project half way though to learn the base of the code. This way it allows the new coder to see every class that is related to the application and they would be able to understand most of the code that was written before him. Finally, with technology evolving every day refactoring code to adapt to those new technology is a much cleaner and easier option to do then to write a brand-new code to adapt to the new technology that is out on the market today.
Some of the bad reasons to refactor code is to make the code look prettier. Most of the time coders would look back after a few days or weeks because the code they wrote was just ugly and wants to go back and fix it. However, that is a waste of time and money for both the coder and the company. If the code works fine you should not refactor the code just for the sake of refactoring. Another reason is to integrate new useless technology. When you are refactoring your code to integrate it for a new technology you should take a step back and think about what does this new technology bring to the table of your product and would it be worth it to even refactor the code for something that is just a one hit wonder.
I like this blog because it is from an experience developer and his own opinion of when it is good to refactor code. I think this topic is very good to learn because in school we are always changing out code to make it look nice and make sure it works so we are constantly refactoring it but in the real world we would not have the luxury to keep changing our code to make it look nice and to just re work it all together. So this blog gives you a good base of when you should refactor your code and when you shouldn’t
