What is review?

Learn that code review is a quality control tool.

What is code review?

Code review is the process of having another developer examine code written by a developer. The goal is not only to find bugs but also to improve code quality, evaluate readability, and suggest improvements.

function calculateTotal(price, quantity) {
    return price * quantity;
}

On GitHub, reviews are usually performed through a Pull Request (PR). The reviewer evaluates the changes and provides feedback.

Why is feedback important?

Issues found during a review are communicated to the author as constructive feedback. A comment can explain why something is problematic and how it could be improved.

// Use a more descriptive name
function getUserAge(birthYear) {
    return 2026 - birthYear;
}

A good review evaluates the code rather than the person and focuses on constructive solutions.

Exercise Create review information

Create a JavaScript object named review. Set the quality and feedback properties to true and the status property to "pending". Finally, print the status value using console.log.

Show example solution

const review = {
    quality: true,
    feedback: true,
    status: "pending"
};

console.log(review.status);
