Source code is an invaluable resource that provides precious context, knowledge, and understanding for any given project. As such, it must be protected and preserved. Since source code is constantly being written and modified by various developers, it’s easy for different versions to sprawl out of control, which can lead to bugs and incompatibility.
This is where version control tools come in, providing an organized way to track changes over time. They record changes so that specific versions can be recalled later, synchronize versions to make sure that team members don’t make different code changes, and provide process enforcement and permissions. Version control is absolutely essential for modern software development, regardless of the size of the project.
