  1. Common Clean Code Challenges

    These are common challenges people face when gaining expertise in clean code. Tackling these challenges head-on can help you learn this skill quicker.

    I'm a junior software engineer working on a team with experienced developers. I often receive feedback on my code reviews that my code is not clean and lacks organization. I struggle with understanding what exactly constitutes clean code and how to implement it in my work. What are some best practices and guidelines I can follow to write clean code? How can I make my code more organized and readable for others?
    I'm a software engineer working on a legacy codebase. The codebase is poorly structured and lacks consistency, making it difficult to understand and maintain. I often find myself spending a lot of time deciphering the code and making sense of its logic. This friction is slowing down my development process and impacting my productivity. How can I refactor the codebase to improve its structure and readability without introducing new problems?
