Even with all the code review tools out there, not every team or company reviews their code before pushing it live.

Code reviews are crucial to ensure code quality and prevent stressful urgent bug fixes. Effective code reviews will make applications easier to maintain, reduce the number of bugs, and spread knowledge among team members. It is important to make sure reviews improve code quality while keeping team morale in mind. Without an effective code review process, you may have to deal with these problems:

Fixing bugs late at night or on weekends
Have trouble maintaining or making changes to your project's code
Have trouble understanding other developer's code
Your team and project do not improve over time

You Need Code Reviews helps you learn everything you need to avoid those problems. The book covers everything from introducing reviews to teams that haven't done them before to how to perform and respond to peer reviews. You will learn how to be empathetic and deal with the human side of code to make reviews a process your team wants to be part of. Whether your team already does code reviews or is looking to improve the process, you will find useful advice within You Need Code Reviews.
