What is the main function of version control in software development?

The primary function of version control in software development is to record changes to files over time. This allows developers to track modifications, revert to previous versions, and collaborate effectively with others by managing different versions of code. Each change is logged, and a complete history of the project's evolution is maintained, making it easier to understand what changes were made, when they were made, and by whom. This is crucial for tracking down issues, maintaining the integrity of the project, and coordinating contributions from multiple developers.

In contrast, compiling code into executable files pertains to the build process rather than version control. Monitoring server traffic and performance relates to operational aspects of applications, while creating user documentation and help manuals is part of the user support process. These functions support software development but do not involve managing or recording changes to the codebase itself.
