So both interested parties can satisfy their needs thanks to code review. Today we’ll clarify what a code review is and what benefits it can give to all.

What is a code review and a peer review?

As you can guess from the name, a code review means a check-up of a source code. As something could be unnoticed during the web development, reviewing the code allows you to find bugs and vulnerabilities and then be able to fix them. This practice improves the code quality of the web product.

A code review is sometimes referred to as a peer review, because the code written by one programmer is examined for errors by a colleague.

  • Code review unifies a development team

This practice Team members express their thoughts on review discussions. This brings them closer to each other and saves them from working in isolation. An open atmosphere in the team provides coherent cooperation and better results from collective work.

  • Code review helps getting familiar with the web project

When a team builds a new website, web portal or application, the work is divided. So usually every team member contributes to the overall project’s success by working solely on their own part. Code reviews allow developers to familiarize themselves with the work of others within the common web project and with the code that they haven’t written, but may have to maintain in future.
