Which of the following is a formal or informal review of programming instructions?

A code review is a formal or informal process where programming instructions, or code, are examined by one or more developers. This process aims to identify bugs, ensure compliance with coding standards, improve code quality, and facilitate knowledge sharing among team members. Code reviews can be conducted in various ways, including peer reviews, pair programming sessions, or through tools that allow for asynchronous feedback, making them an essential part of software development and maintenance practices.

The focus during a code review is not only on verifying that the code functions properly but also on ensuring that it is efficient, maintainable, and secure. This collaborative check can prevent potential issues from reaching production and encourage adherence to best practices within the development team. Such thorough scrutiny ultimately leads to higher-quality software and reduced risk of vulnerabilities in applications.
