How can you debug without introducing new bugs?

4 Follow coding standards

Coding standards are guidelines and best practices that define how to write and format your code. They can help you debug without introducing new bugs by making your code consistent, clear, and easy to understand. Coding standards also prevent common errors, such as syntax errors, naming conflicts, or logic flaws. Some popular coding standards are PEP 8 for Python, Java Code Conventions, and Google C++ Style Guide.

5 Review your code

Code review is the process of examining and improving your code by yourself or with others. It can help you debug without introducing new bugs by finding and fixing any mistakes, bugs, or vulnerabilities that you might have missed. Code review also enhances your code quality, performance, and security. Some popular code review tools are GitHub, CodeGuru, and CodeClimate.

6 Learn from your bugs

Learning from your bugs is the attitude and habit of analyzing and understanding why and how your bugs occurred, and how to prevent them in the future. It can help you debug without introducing new bugs by increasing your knowledge, skills, and confidence as a developer. Learning from your bugs also fosters a growth mindset, a curiosity, and a passion for coding. Some popular ways to learn from your bugs are reading documentation, tutorials, and blogs, asking questions on forums and communities, and keeping a bug journal.
