Clean Code Principles

In this blog post, Marcus Biel gives his thoughts on clean code, what that is, how to implement, estimate, and accurately design good software that does exactly what it should and nothing more. What is clean code? The author writes,

“It’s the idea that your code should be precise and as close to perfect as possible. If you have more code than you need, it shouldn’t be there.”

This concept relates to YAGNI (you ain’t gunna need it), and is an essential part of having clean and readable code. Adding features that might be needed later is a good way to bloat your code and run into bugs. Clean code requires time to fully understand the problem, this is sometimes tough when working in an environment where you are being pushed by those who don’t understand what goes into software design. Sometimes you will be asked to meet deadlines that will make you rush, in turn you can end up with poorly written code. The language and wording in code is also very important, using variables and names that are clear and make sense help others read and understand what is going on in your code. I selected this resource because having clean code is a huge part of being a good programmer, along with tips on clean code, the author has tips on designing code by running tests first, working with co-workers and clients to understand what features are most important, and what features are not beneficial.

“To me, being a software craftsman is about having a focused attitude and about taking responsibility for your code, your job, and your time. So, from beginning discussions to end results, your one focus should be on maintaining your own high standards and creating the best possible product for your client.” – Marcus Biel

This post had a good amount of information and insight on clean code, and being a good developer in general. Important aspects from the post I think are being clear when naming variables, methods, and classes, leaving out code that is not needed (YAGNI), and making accurate timelines for projects. Rushing to write code before you fully understand the problem can lead to more problems down the road. I expect to use concepts of clean code in my professional career, I believe it’s very important to make a good product that will benefit you, your company, or your client.
