Version control [ˈvɝː.ʒən kənˈtroʊl]: systems that manage changes to code over time.
A version control helps developers to keep track of the old versions of a project and – if a mistake was made in the new version – jump back to them. It also enables them to work on the same project at the same time: It stores the two parallelly made modifications in seperated branches that later can be merged.
