The result illustrates the difference between doing something you’ve read about and doing something you’ve seen. Readable code is great, but not all code will be immediately readable.
Why is it a good idea to review code?
So, what exactly is a good code review and how to achieve the idea? Read this article to learn the ins and outs of code review best practices from our team at Codete.

The peer review process also benefits from holding team members accountable. This means conducting follow-up investigations to verify that there are no defects within the code prior to moving into production. In addition, code review promotes the flexibility to build new features instead of spending time analyzing existing code. This means that there is scope for innovation within the software development process. As your code base grows and the many contributions from different team members come together, stylistic differences can take a toll on productivity. This issue can balloon into a show-stopping problem that effectively cripples development momentum and needlessly frustrates your team.
- Also, I guess, it is a good practice for developers to annotate source code before the review.
- Providing feedback can be harmful and unpleasant if you don’t execute the review process properly.
- However, aSmartBear studyindicates a considerable decline in defect density at speeds quicker than 500 LOC per hour.
- By using external and internal metrics, you can decide whether the code review needs revising or it’s going in the right direction.
The fundamental purpose of a code review process, as described earlier in this article, is to enhance efficiency. While the traditional code review approaches outlined above have worked in the past , you may be losing efficiency if you haven’t switched to using a code review tool. A code review tool automates the code review process, freeing up the reviewer’s time to concentrate solely on the code. Your ultimate guide to Heroku custom domain name Code review is vital, but it can also be a time-consuming as well as a painstaking process.
