Why Code Reviews Matter
In my experience, the teams with the best code review practices ship higher quality code, onboard new engineers faster, and maintain better team cohesion. But bad code review practices can be toxic and slow teams down.
The Review Mindset
Approach reviews with empathy and curiosity, not judgment. Ask questions like “Can you help me understand why you chose this approach?” instead of “This is wrong.” Remember, you’re reviewing code, not the person who wrote it.
What to Look For
- Correctness: Does it solve the problem?
- Design: Is it well-designed for maintainability?
- Complexity: Is it simpler than alternatives?
- Tests: Are there appropriate tests?
- Naming: Are variables and functions clearly named?
Speed Matters
Review PRs within 24 hours. Long review cycles kill momentum and lead to larger, harder-to-review PRs. Block time on your calendar for reviews—they’re not optional work.
