Version control is a process by which software developers maintain different versions of the code they write in a structured manner. This allows them to go back to any previous code version called a commit. These commits allow developers to go back to the previous version of code and even pick a piece of code out of a previous commit and apply it to the current version.
These commits allow developers to save their work to the Any application or website that is written is developed using code of a specific language. That code is called the... repository, which can maintain all the different pieces and functionalities the development team is working on. This allows teams to work on multiple features in separate branches in isolation, which can all be merged together.
Version control is a must in software development. Otherwise, entire projects will be copied, and you will end up in a situation where you have a copy of a project and then a copy of a copy of a project, and not know which is the most up-to-date and accurate version.
