A Code Review Checklist is a set of guidelines and standards for reviewing code. It helps ensure code meets the standards for readability, security, scalability, and performance. The checklist includes questions like: Is the code well-commented? Are there any security issues? Is the code maintainable? Is the code efficient? Does the code adhere to coding standards? Are there any redundancies or unnecessary code? Is there adequate test coverage? The checklist helps developers to ensure the code they write is of the highest quality and is fit for purpose.
