What is the purpose of a version control system (VCS)?

The purpose of a version control system (VCS) is to manage changes to source code over time. A VCS enables developers to track the history of modifications made to code, collaborate with other developers, and maintain different versions of code in a structured way. It allows teams to record who made specific changes, when those changes were made, and the nature of the changes, which is crucial for maintaining the integrity and consistency of a software project.

Moreover, a VCS facilitates the process of branching and merging code, making it easier to work on different features or fixes simultaneously without conflicts. The ability to revert to previous versions in case of issues or bugs is another critical aspect of version control, providing a safety net for the development process. Overall, a VCS is an essential tool for managing the evolution of software projects, ensuring that developers can collaborate effectively and maintain a clear project history.
