Clean Code Essentials

This includes indentation, brace positioning, and method organization. When you and your team follow a consistent coding style, it improves code readability and reduces cognitive load.

Choose names that clearly express the purpose of the variable, function or class. Good names eliminate the need for further comments and make the purpose of the code obvious. This exercise will help not only you, but everyone else who reads your code in the future.

Duplicate code is an issue that leads to maintenance nightmares. When you have multiple copies of the same code, changes become exponentially harder to implement. Instead, extract shared code into reusable functions or methods. This technique reduces repetition and makes your code more modular and testable.

Refactoring isn’t just a one-time task – it should be an integral part of your coding process. It helps in maintaining the cleanliness of your code and preventing technical debt.

Overengineering can lead to code that is difficult to understand and debug. Simplicity in your code makes it easier to test, reduces the likelihood of bugs, and increases readability.

While your code should be as self-explanatory as possible, comments are sometimes essential to provide context and explanation of the code. Focus on describing the "why" rather than the "how". Avoid commenting on every line of code, instead provide a title or summary of a piece of code that explains its purpose.

The tests provide a safety net to detect errors early. In addition, good testing practices help ensure that code works as expected and make refactoring and upgrading safer and easier.

Writing clean code is a skill that will benefit not only your current project, but your entire software engineering career. By applying these practices, you will increase both the quality of your work and your value as a team member.
