Five reasons why developers need to perform Code Review

Everyone acknowledges that Code Review is costly and time-consuming, especially when software projects are sent to the software testing department. For some developers, it will lead to more office politics and gossip.

A code review may gradually improve the code. If you think that you have only slightly improved the software from a valid code review, you need to think about it again. The reasons that are easy to ignore in the following five points will give you some inspiration.

　　1. If developers know that their code will be evaluated, they will work harder.

What is most useful for code review is to let programmers know that the code they write will be reviewed. This is like a final exam with a 400 level of computing content. It doesn't matter whether you take the test, because the purpose of the test is to learn computing.

This principle also applies to code review. Computer programmers are always quite confident in their own code. Programmers stay up late because they really love their jobs, not for money or other purposes. Therefore, code review can directly affect developers' sense of accomplishment.

Programmers do not want any criticism of their code, so once they know that the Code will be reviewed, they will take additional efforts to do a good job. In fact, code reviews generally do not find anything. However, if you know someone wants to review the code, the programmer will do as well as possible during the editing process.

　　2. Code review can improve developers' Programming Technology

In your mind, you may not care too much about the success of a specific software project. However, most programmers want to improve their technology, which means learning from others. There is no better learning opportunity than code review.

For example, from the coding of a good developer, you can better understand what a programming language can do, and you will learn to write more effective code, and find more patterns that can be used to organize code.

Code review can help team members learn from each other's mistakes and become better programmers. Through simple feedback, the company can improve the level of its developers. Developers value review as they know that this will help them grow. The entire team was improved when code reviews were conducted in groups. But it is better that the code quality is also improved and easy to maintain.

　　3. Code review is conducive to the mentor system, and programmers will learn more

Code review helps train new developers and familiarize them with other similar modules. The review process facilitates exchange of ideas and reusable code.

Code review has a systematic approach to provide a platform for programmers to share their experiences with team leaders. It is very exciting when leaders rewrite some programs and increase the program running efficiency by 50 times in 3 minutes! When writing other programs, you may find some new methods or create a new solution.

　　4. Code review can realize the inheritance of high quality culture

The purpose of code review is to provide great opportunities. Code review gives both the code library and the coding team the opportunity to develop a consistent and reliable model. It leverages teams with experience and expertise as a whole, allowing programmers to refine their professional skills and experience while serving the company and team with their experience and expertise. This gives the company a tangible return on investment: The ability and consistency of pleasant programmers and work code are constantly improved.

Code review helps create a subtle change, so managing well and doing well with code review can greatly improve software quality. Developers will quickly complain about the determination of erroneous data in the review, but we must change the rules and take high quality and efficient development as a measure of the process, not just a milestone in the transfer of value.

　　5. Code review can stimulate team cohesion

People think that code review is just looking for vulnerabilities, but it can bring people together and it can provide much more than you expected.

There are many other such examples that occur when performing code reviews, but the best way to success is to review when a team is formed. The longer you work on a project, the better the quality of the code you create. This is because all code review processes and management start at the beginning of the project.
