Code Review, also known as Peer Code Review, is the act of consciously and methodically assembling with one's fellow programmers to examine each other's code for errors. It has been consistently proved to expedite and streamline the software development process in ways that few other methods can.
The fundamental goal of code review is to ensure that Google's code base's general code health improves over time. To that goal, all code review tools and processes are created. A succession of trade-offs must be balanced in order to achieve this.
Code reviews are quality assurance procedures that assess a developer's code in respect to a number of objectives. The primary goal of code reviews is to detect code flaws, but they also check for QA compliance in terms of logic, structure, style, and readability.
There are three types of code review practices: pair programming, formal code review, and lightweight code review.
