Code is the foundation of any software product, whether a website or a mobile app. The more consistent this basis is, the easier it will be to deal with it, for example, if the project has to be modified.
The following are the primary characteristics of high-quality code: readability, flexibility for alterations, updatability, and comprehensibility. However, project work is frequently completed hurriedly. As a result, even the most experienced software engineers do not always create the best quality code. As a result, a code review technique is carried out to enhance the code’s quality.
Other software engineers examine a particular engineer’s code to verify for conformity with standards, discover mistakes, disclose disparities in coding style, and test the written code’s applicability for a certain set of objectives.
This post will explain how the whole procedure works and the benefits and drawbacks of such labor. We’ll also go over the best practices for code review.

An Overview of the Code Review Process
The goal of this project is for any changes made by the developer to make it into the main code repository, where they will only be published when the rest of the team has reviewed them.
There are several stages to the code review process:
- The programmer adds new features to the code and asks his colleagues to double-check the changes.
- Reviewers go through the code and provide feedback. Furthermore, it is preferable to concentrate on more than just discovering flaws. To significantly enhance code quality, it’s also vital to point out architectural problems or bad coding styles, whether confusing or difficult to understand.
- Working with comments is the next phase in the code review process. If writers disagree with a claim, they may reject it, but they must explain their position with compelling reasoning. They make the appropriate modifications if they cannot develop any arguments.
The whole process is repeated whenever a new set of alternations is added to the code.
Who is in charge of code review?
Senior developers undertake code reviews, with middle developers reviewing juniors, seniors reviewing middles, and other senior developers or team leaders reviewing seniors. If the organization is big enough, multiple committed persons may be assigned to examine everyone’s code and maintain the overall style.
If the team is small, the lead developer performs code reviews while keeping an eye on the project and other developers’ work quality.
What Are the Advantages of Code Review and Why Is It Important?
When the code review process is done properly, it gives various advantages that are essential both collectively and individually.
The ability to correct errors that may cause problems in the future; team compliance with standards and code style; improving solution architecture and design; verifying code compliance with the task; improving overall code quality; professional development of coders; forming consistency in making specific decisions in the team
The so-called bus factor is decreased due to code review since it is simpler for someone to understand how everything works when moving a project to another team or enticing a new individual to the job.
In general, developers who know their peers will evaluate their work prefer to produce nice and organized code, which improves the code’s quality.
Despite all of its benefits, code review has certain drawbacks. Only two come to mind. The first is the duration of the process since some individuals must spend time reading the code while others must correct it. Another downside is that the cost of project execution will be higher since the developers’ time must be compensated.
When Code Review Isn’t Necessary
Despite the apparent advantages of code review, it is feasible to go without it in certain situations.
When designing a prototype product or MVP, doing a code review (minimum viable product) makes no sense. A project like this is often used to verify a concept, get customer input, or test ideas for future product development. Developers will still have to significantly recode such a project in the future since any MVP is always designed as basic as possible.
Furthermore, code review is unnecessary for basic programs that are only used once and have no intentions to be changed in the future. As a result, if you have no plans to amend or change your project in the future, you may save time and money.
To Sum Up
Software development would not be complete without code review, and when done correctly, it benefits the whole team. If you incorporate a process into your job, you must first identify clear objectives to reach. In this instance, you will accomplish optimum productivity without being sidetracked by unneeded stuff.
