Source control is a system that allows developers to manage changes to their codebase over time. It allows developers to track and collaborate on changes, as well as revert back to previous versions if needed. Source control also allows for multiple developers to work on the same codebase at the same time, without stepping on each other’s toes. This is done by having each developer work on their own branch, which is then merged into the main codebase when it is ready. This allows for a much smoother development process, as well as better collaboration between developers. Source control also allows for better tracking of bugs and other issues, as well as a better way to keep track of changes that have been made over time. In short, source control is an invaluable tool for any development team, and is essential for any successful project.
