How To REALLY Do Code Reviews

Code reviews exist on a spectrum from extremely strict (Linux kernel style) to laissez-faire, and the right approach depends on multiple variables: the experience levels of reviewer and reviewee, ego management, project type (open source vs. commercial), team location, and available time. Using a real GitHub pull request for a Google Photos clone as an example, three approaches to code review are demonstrated: high-level nudging comments for senior developers, detailed specific feedback for junior contributors, and outright rejection with explanation for personal projects. The core takeaway is that there is no single correct way to do code reviews — context determines everything.
