code review
A second set of eyes checks your changes before they become part of the app.
Like a coworker proofreading a letter before you mail it, code review is someone else checking your changes.
It helps catch bugs, share knowledge, and keep a consistent style. Reviews happen on pull requests, a proposal to merge a branch.
In this course, CodeRabbit comments first, then a human approves or asks for edits before merging. That way the main branch stays healthy.
