Writing code is easy! A newbie into world programming can learn to write code in minutes. Don’t believe me? Just remember your first “Hello World” program, how easy was it.
But writing clean code is a really tough job to accomplish. It requires lots of practice and dedication. I assure you that you will write a more beautiful and cleaner code by end of this post.
What is clean code? In short, it is a code that is easy to understand and easy to change.
Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year countless hours and resources are wasted due to bad code.
If you write clean code, then you are helping your future self and your co-workers. With such code, you are reducing the cost of maintenance of the application you are writing, and fixing bugs will be easier.
But there is a problem when learning to write clean code. The problem is that there are so many practices and tips on this subject it can be overwhelming. As a result, It can be difficult for developers to choose these tips and tricks and are often overwhelmed.
Let’s make this process easier. In this article, we will first discuss some advantages of writing clean code so that you know why we write a specific type of code.
Then, we will take a look at the best five tips, or practices, for writing clean code, that developers use most often.
Let me demonstrate this in one simple example. Let’s say that we return to one of our projects after a very long time. Maybe, one of our previous clients got in touch with us and hired us for another work.
Now, let’s also imagine that, back then, we were not writing the cleanest code, rather we were doing the opposite. Right after the first look, we see how bad and messy the code is. And, we can also already see how hard it will be to start where we left off and are demotivated.
As a result, we now have to spend more time on that project than it is required to because we have to understand that messy code we wrote in the past. We could have avoided this time wastage if we had written clean code from the start. And we do what most developers do when in trouble, start over!
If had we written Clean code, that would have rectified our problem. Maybe we will need to read the code for a few minutes to understand how everything works.
