Hello everyone
For this week’s blog topic, I will talk about clean code. This was one of my favorite topics that we have discussed in class so far. Even before, I knew that writing good code is important, but I was unsure on how clean code was written. So far I had an idea, from doing exercises, solving problems and writing my own projects either for school or for fun. I thought my code was good enough that it would pass Uncle Bob’s test of clean code, but after reviewing again through his perspective it definitely does not pass as it needs a lot of improvement. Clean code is extremely significant as also stated by the author of the blog, writing code may take up 10% of a programmer’s time while reading and understanding code occupies the remaining 90%. In the blog, the author mentioned how this is even more accurate as in an open-source project like his, where external contributions can be done. The code needs to be clean enough, so the contributors can easily understand and spent most of their time writing code to add to the project. If the code was written poorly, it would make the experience of the contributor a nightmare as he would spend double of his time just reading and understanding, which would leave barely any time to add any new features. If the project goes to be used by multiple users, bugs would eventually pop up and fixing them in a timely manner when the code is a mess it would be very annoying. Even adding new features, it would be extremely time-consuming as you have to do twice the work if the code was written good. This is one of the reasons why I chose this blog from the rest. The author emphasizes the real problems that come with writing bad code and how much it will cost you time wise to maintain your project up and running.
Later on the blog, the author points out the importance of functions and formatting. These are two simple things that anyone can learn and apply it to any of their work.
Some key points that I wrote down for myself were that functions should be kept small and compact. The principle states that small functions increases clarity and reduces clutter. It makes it easy on the eye as it scrolls through the code, knowing what the function does and where it is used in an instance. The second point he mentioned was both vertical and horizontal formatting. He compared it to the Newspaper Metaphor, which it suggested that code should present key information at the top. It is also important to create vertical spaces between different functions which allows separations, and creating a format which is followed throughout the rest of the project.
Horizontal formatting focuses more on maintaining manageable line lengths. We don’t want the lines of code to be too long, and they should be viewing compatible for every screen size. It is not recommended and always avoided scrolling horizontally in your code as it can become annoying over time and time-consuming. This code in a way was a reflection of my journey towards Clean Code. I had similar mistakes that I did in that past not knowing how to write clean code, but after reading more about it now I am capable of writing clean code. This is a valuable skill that my future self will thank me for mastering!
