Developers use version control systems (VCS), such as Git, to manage changes in code during software development. VCS tracks revisions, allowing developers to collaborate efficiently, revert to previous versions, and maintain a history of modifications. This streamlines teamwork by enabling multiple contributors to work simultaneously without conflicts. Through branches, developers can experiment without affecting the main codebase, which promotes testing and innovation. Additionally, VCS enhances accountability by recording who made specific changes, fostering transparency and facilitating easier troubleshooting in the development process.
