We spend more time reading code than writing it, so good code quality is the most important aspect of programming

In this course students can learn why code quality is the most important in programming, what is the difference between good and bad code and how to write a good one.

Clean and readable code is vital in programming because it improves collaboration, maintainability, and scalability. Code that is easy to understand allows developers to quickly grasp its purpose and logic, making it easier for teams to work together, especially in projects with multiple contributors. Readable code minimizes the time required for debugging and updating, as developers can easily identify and fix issues or implement new features without extensive rewrites.

Well-structured and clear code also enhances the long-term value of a project. As projects evolve, clean code makes it easier to adapt to new requirements or technologies. Conversely, messy or poorly written code can lead to technical debt, where maintaining and improving the software becomes increasingly costly and time-consuming.

Adhering to clean coding practices—such as meaningful naming conventions, consistent formatting, and clear documentation—ensures the code is accessible not only to its original authors but also to future developers. Ultimately, clean code promotes efficiency, reduces errors, and fosters a sustainable development process.

The course is going to focus on how these good traits can be added to your daily programming habits. In pair with the good ones, bad traits will be discussed, too.
