Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. It is a crucial tool for developers as it allows multiple people to work simultaneously on a single project, managing changes made by different individuals without overwriting each other's work. This system supports collaboration and can prevent conflicts between concurrent changes by providing features such as branch management, merge tools, and conflict resolution.
Popular version control systems include Git, used with platforms like GitHub and Bitbucket, which are essential for maintaining the integrity and history of project code. Version control not only facilitates better coordination among team members but also provides a safety net for recovering lost work and analyzing changes over time.
