The goal is to **improve the code's quality, security, and readability**, not just to "catch errors". ### Main stages of code review 1. **Creating a pull request (PR)** The developer finishes the task, makes a commit, and opens a PR in the repository (for example, on GitHub, GitLab, Bitbucket). The description states the purpose of the changes, the related task, and the list of files and tests. 2. **Reviewers review the code** One or more colleagues read the changes line by line. They check: - correctness of the logic, - readability and style, - presence of tests, - impact on performance and security, - adherence to architectural principles. 3. **Comments and discussion** Reviewers leave comments directly in the code. The author discusses them, makes fixes, or explains decisions. This is a key moment for exchanging knowledge and aligning standards. 4. **Fixes and re-review** After the fixes, the author updates the PR, and reviewers look at the changes again. 5. **Approval and merge** When everyone agrees, reviewers give "approve", and the code is merged into the main branch (often after automated tests). ### Goals and value - Improving **code quality and stability**. - Early detection of errors and architectural problems. - **Knowledge sharing** between developers. - Consistent standards and approaches in the project. ### Conclusion Code review is not control, it is a **collective defense of product quality**. A good review does not slow down development; it makes the team stronger, the code more reliable, and the knowledge shared.For the reviewerNote to the moderator (optional)Visible only to the moderator.
