How long should a code review take?

A review should take 15–60 minutes. If a PR takes longer to review, it is probably too large. Keep PRs under 400 lines of changes for effective reviews.

What should reviewers focus on?

Logic correctness, edge cases, security implications, design decisions, and test coverage. Let automated tools handle formatting, linting, and style — humans should focus on things machines cannot check.

Code Review Process Explained

Systematic examination of every code change — the practice that catches bugs, shares knowledge, and maintains quality.

Code Review Process

A quality assurance practice where one or more developers examine code changes before they are merged, checking for bugs, design issues, and adherence to standards.

Explanation

Code review catches bugs, improves code quality, and spreads knowledge across the team. A reviewer checks for correctness, readability, test coverage, security issues, and adherence to coding standards. Good reviews are constructive, specific, and timely (within 24 hours). They should not be rubber stamps or adversarial gatekeeping. Automated tools (linters, type checkers, CI) handle mechanical checks, freeing reviewers to focus on logic, design, and intent.
