What is the main aim of a code review?

The primary aim of a code review is to identify vulnerabilities and improve code quality. During a code review, developers examine each other's code to find potential issues, such as bugs, security vulnerabilities, and areas where the code can be optimized or made more maintainable. This collaborative practice not only enhances the quality of the code but also helps in sharing knowledge among team members and ensures that best practices are being followed.

In addition to improving the intrinsic quality of the code itself, a thorough code review serves to catch mistakes early in the development process, which can lead to significant time and cost savings down the line. By addressing these potential issues before the code is deployed, the overall reliability and performance of the software can also be enhanced.

Other options, while they may touch on important aspects of software development, do not directly align with the main aim of a code review. For instance, testing the software's performance is a different process altogether that typically comes after the code is written. User acceptance criteria are usually related to ensuring that a product meets the expectations of stakeholders rather than focusing specifically on the code itself. Finally, preparing project deliverables is a broader task that involves documentation and completion of tasks rather than the focused activity of reviewing code.
