A Comprehensive Guide to Conducting Code Reviews on GitHub
Code reviews on GitHub are an important part of the software development process. They allow developers to collaborate on a project, review each other's code, and improve the overall quality of the codebase. In this guide, we'll discuss what code reviews are, why they are important, and how to effectively conduct a code review on GitHub.

What are code reviews?
Code reviews are a process in which one or more developers review the code written by another developer. The goal of a code review is to identify potential issues, bugs, and improvements in the code. Code reviews can be conducted for any type of code, but they are commonly used for large, complex projects where multiple developers are working on the same codebase.
Why are code reviews important?
Code reviews are important for several reasons. First, they help improve the overall quality of the codebase. By having multiple developers review each other's code, they can identify potential issues and bugs that may have been missed during the initial development process. This can save time and effort in the long run by preventing the need to fix these issues later on.
Second, code reviews can help improve the collaboration and communication within a development team. By reviewing each other's code, developers can learn from each other and share best practices. This can help foster a more collaborative and productive work environment.
Third, code reviews can help new team members get up to speed on the project. By reviewing code written by more experienced developers, new team members can learn how to properly write and structure code for the project.
How to conduct a code review on GitHub
Conducting a code review on GitHub is relatively straightforward. Here are the steps to follow:
Start by creating a new branch for your new code. This will allow you to make changes to the code without affecting the main branch.
Once you are done coding, publish the new branch and create a pull request on GitHub. Invite other developers to review the code by using the "Reviewers" feature in GitHub. This will allow the invited developers to access the code and provide feedback.
The reviewers will then begin their review by looking at the code and commenting on any issues, bugs, or improvements they find. These comments will appear in the "Conversation" tab on the GitHub page for the branch. Again, this process can be speed up by using What The Diff before digging into the code.
As the reviewers make comments, you can respond to them and discuss any potential changes. This can be done by commenting on the code directly, or by using the "Files changed" tab to view the changes and discuss them in the "Conversation" tab.
Once the reviewers have provided their feedback and any necessary changes have been made, the code can be merged into the main branch. This is typically done using the "Merge pull request" button on the GitHub page for the branch.
In conclusion, code reviews on GitHub are an important part of the software development process. They help improve the quality of the codebase, improve collaboration and communication within a development team, and provide an opportunity for new team members to learn from more experienced developers. By following the steps outlined above, you can effectively conduct a code review on GitHub and ensure that your code is of the highest quality.
