Code Reviews: How To Effectively As Well As Politely Critique Code

Here, What do you think, is the most significant benefit of an effective code review?

Is it improved code quality?

Or is it a reduction in the total number of defects?

Hence, The biggest benefit of a successful code review is “expanded expertise”.

Therefore, Reviews are less about deformity than expected as well as instead provide additional benefits such as:-

• Knowledge transfer
• Increased team awareness, as well as
• The creation of alternative solutions to problems.

When our awareness boosts, we become better programmers, designers, as well as architects. A team of highly knowledgeable programmers produces well-architected as well as conceivable code. As a repercussion of generating well-designed code, we start to see devaluation in glitches and expanded traits. The author, as well as the reviewer, are the two main stakeholders of a code review.

Authors

1. Always cross-check your work before submitting it for review

Here, Always treat the code you write as a great work of art. We should always aim to submit our best work. This does not mean you should be beset over cleaning every inch of your code. It means that you should take care of the frivolous things like code style as well as variable names before anyone else look at the code. Also, make sure that you comply with your team’s coding standards. You can clout a static code analysis tool to help with this.

2. Provide background around the code that you have written

Hence, We cannot always consider whether the reviewer will accept the functionality of our code. This is true if you have worked on a brand new piece of functionality all by yourself. In this scenario, you are the only one who knows the code inside out. Providing context upfront should help avert probable confusion.

3. Always have a trial of your code before you submit

If your company has a fully automated Continuous Integration (CI) pipeline, the clout that to test your code. If not, thoroughly test it narrowly. Don’t expect the reviewer to test your code for you.

4. Keep it pithy

Try to submit short code reviews. Humans generally cannot course a lot of information in a short period very well. When you submit lengthy code reviews the reviewer will tend to skip over the core functionality as well as the logic of your code. They can become overwhelmed with a large amount of information and will most likely spend less time reviewing your code.

Reviewers

1. Give Positive feedback

As a reviewer, always provide positive feedback to the author. Constructive feedback helps drive an essential conference. This encourages the author to understand your point of view. It can also lead to a great learning experience. Code reviews are not only for pointing out areas for improvement. They are also meant for giving applause to the author when they have done a good job. Don’t forget to give praise when it is deserved. When the author writes commendable code, the other reviewers can learn from it.

2. Be Cognizant of tone

Instead of providing feedback like “What were you thinking?”, “What you’ve done here is incorrect”, “Why didn’t you do it?” say things like “Could we try?”, “What do you think about?”, and “What happens when?” Being polite will lead to a conversation, instead of receiving an opposing response or no response at all.

3. Grasp Together

Teach what you know, learn what you don’t know. Code reviews provide enormous freedom to collaborate. Grasp this idea. Reviewing code not only makes you a better programmer but also a great counsel. You may understand a concept even better when you teach it to someone else.

4. Everyone should review the code

Everyone on your project team should do the code review. It should not be entirely submitted to the senior developers. This is because participating in code reviews encourages junior developers to learn quickly. It is also possible that a junior developer is more knowledgeable in a certain technology or a concept than the other developers on the team.
