What does "code review" mean in programming?
code review is one of the most common terms in software development. This guide explains what it means, how it is used in practice, and why it matters, with real examples from the developer world.
Definition
The practice of having one or more engineers read and comment on another engineer's code changes before they are merged. Code reviews catch bugs, enforce standards, share knowledge, and improve code quality. Reviews are conducted on pull requests and can result in approval, change requests, or blocking comments.
Example
"Code review caught a missing null check before the PR was merged — exactly what reviews are for."
