TLDRLearn 10 coding principles that will help you write clean, maintainable code. From coding style and comments to error handling and testing, these principles will elevate your code from average to great.

Key insights

🖊️Coding style and adhering to style guidelines ensures consistent and readable code across teams.

💡Including helpful comments improves code clarity and provides context for future developers.

🛡️Implementing error handling techniques like proper error logging and exception handling enhances code robustness.

🌐Using abstractions and design patterns like SOLID principles improves code organization and maintainability.

Writing clean code that is easy to test reduces bugs and allows for confident code changes.


Why is coding style important?

Coding style ensures consistency and readability, making code easier to understand and maintain.

Why should we include comments in our code?

Comments provide clarity, explain design choices, and make code easier to understand and debug.

What is error handling and why is it important?

Error handling is the practice of anticipating and handling errors to prevent crashes and unpredictable behavior in code.

What are SOLID principles and why should we use them?

SOLID principles are a set of guidelines that promote modular, maintainable code. They improve code organization and flexibility.

Why is testing important in software development?

Testing ensures that code is functioning as intended, reduces bugs, and allows for confident code changes.
