Code review is a team process where colleagues look at each other's work to catch mistakes and share knowledge. It ensures the final product is high quality and helps everyone learn from each other.

The Purpose of Reviewing

Breaking work into small pieces makes it much easier to understand and check. Large changes are often overwhelming and lead to missed errors.

Reviewing in Small Chunks

Feedback should always be respectful and focus on the work, not the person who did it. Using positive and helpful words keeps the team motivated.

Using Kind Language

The most important part of a review is making sure the instructions actually do what they are supposed to do. You must verify that the new changes solve the intended problem correctly.

Checking the Logic

Instead of demanding changes, ask questions to understand why a specific approach was chosen. This encourages healthy discussion and better problem-solving.

Asking Helpful Questions

Don't just look for mistakes; point out when someone writes something clever or clean. Positive feedback reinforces good habits and builds team spirit.

Celebrating Great Solutions

Computer programs can automatically catch simple typos and formatting mistakes before a human even looks at the work. This saves time so reviewers can focus on more important issues.

Using Automated Checkers

When you ask for a review, provide a short summary of what you changed and why. Giving this background information helps the reviewer understand your goals quickly.

Explaining Your Changes

Always check your own work one last time before asking others to look at it. This helps you catch obvious errors and shows respect for your teammates' time.

Reviewing Your Own Work

Try to give feedback or answer questions as quickly as possible. This keeps the project moving forward and prevents work from piling up.

Responding in Good Time

Spend most of your effort on important problems like logic errors or security risks. Try not to get stuck arguing over tiny personal preferences that don't affect the final result.

Focusing on Major Issues

Check the work for any weaknesses that could let unauthorized people break the system or access private data. Safety is a top priority in every review.

Looking for Security Flaws

A review should end with a clear decision on whether the work is finished or needs more changes. This ensures everyone knows exactly what the next steps are.
