In 2023, code quality will be more about maintainability and reliability than anything else due to increased pressure on development teams to release high-quality software on schedule. Key factors for developing a high-quality codebase include maintainability, reliability, testability, portability, and reusability. To improve code quality, developers should use code conventions, write helpful comments, use a linter, refactor legacy code, and follow code review best practices. Automation tools such as static analysis, dynamic analysis, and code review tools are essential for maintaining high-quality software products.
