A pull request is a fundamental component of collaborative software development, particularly in version control systems like Git. It is a formal request to merge a branch of code changes into the main or target branch of a software project.
Pull requests facilitate code review, collaboration, and quality control. Developers create pull requests to propose code changes, and team members can review, comment on, and approve or reject the changes. Once a pull request is approved, the changes are merged into the main codebase.
