What is Code Review?

Having other developers examine your code changes before they're merged

Why It Matters

Code reviews catch bugs, spread knowledge, and maintain code quality across the team

Real-World Example

A teammate suggesting a simpler approach to your solution during review

“Understanding terms like Code Review matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”

Callum Holt, Founder, 13Labs
