Code review is a systematic examination of source code to identify bugs, improve quality, and ensure adherence to coding standards before merging changes into a project.

Explanation:

• A code review is typically conducted by peers, senior developers, or automated tools to detect issues early.
• It helps in catching security vulnerabilities, enforcing best practices, and improving code readability.
• Code reviews can be formal (strict guidelines) or informal (lightweight, collaborative discussions).

Best Practices:

• Use version control tools (e.g., GitHub, GitLab) to conduct pull request-based code reviews.
• Provide constructive feedback instead of criticizing.
• Use static code analysis tools (e.g., SonarQube) for automated checks.
