Code reviewers need to have a strong understanding of programming languages and development processes, as well as knowledge of coding standards and best practices. They also need to have good communication skills to provide constructive feedback to the development team.

Example to explain the role of a code reviewer:

Suppose a software development team is working on a project to develop a new e-commerce website. The team has several developers who are responsible for writing the code for different features of the website, such as the shopping cart, checkout process, and customer account management.

Before the code is released for testing or deployment, a code reviewer is assigned to review the code written by each developer. The code reviewer examines the code to ensure that it meets the required standards of quality, efficiency, and maintainability.

For example, the code reviewer might check if the code is well-structured and organized, uses appropriate naming conventions, and follows best practices for coding in the programming language used. The code reviewer might also check for potential security vulnerabilities, like SQL injection or cross-site scripting.

If the code reviewer finds any issues or potential problems in the code, they provide feedback to the developer and suggest improvements or fixes to the code. The developer then makes the necessary changes to the code and submits it again for review.

This process continues until the code reviewer is satisfied that the code meets the required standards of quality, efficiency, and maintainability. Once the code is approved by the code reviewer, it is released for testing or deployment.
