What is version control?Version control is essentially tracking revisions made to a file or a set of files. A version control system (VCS) allows you to keep a history of changes made, restore older versions of a file, sync files between team members, and more. This makes it easy to fix mistakes like overwriting or deleting files, and helps to keep files up-to-date.
Benefits of version control
Keeps files safeSince version control makes it easy to recover deleted files or restore older versions, your files are safer and more secure. It's one of the most efficient ways to ensure you always have a backup of your files.
Tracks changesA version control system will track all changes to your files, giving you a detailed history of edits and updates. This makes troubleshooting much easier, since you can pinpoint what changes were made that might have broken something.
Makes collaboration easierVersion control systems also make collaboration easier by allowing users to work on a set of files at the same time without worrying about overwriting changes. Most VCSs provide the ability to lock files when in use, and files will update to the latest versions for all team members.
Saves timeAdding version control into your workflow will help streamline the web development process. Projects will take less time with the improved collaboration and file management, and will go more smoothly overall.
"For most developers, version control tools are the most important tools in their toolbox. Every development project starts with choosing the right version control system."
