Code Review in Git & GitHub

Code review is a team process where developers examine each other's code for bugs, style, security, and performance. It's not criticism — it's collaborative improvement. Comments should be constructive and professional.

As a reviewer, look for: correctness, readability, performance, security, and tests. As a submitter, respond gracefully to feedback and thank reviewers for their time.
