🔄 Version Control

Version control is a system that tracks every change to the code, who made it, and when. It lets multiple developers work on the same project without overwriting each other's work. The most popular tool is Git, used with platforms like GitHub.

📖 Key Version Control Features

Feature	What It Does	Collaboration Benefit
Branching	Each dev works on their own copy	Nobody overwrites anyone else's work
Commits	Save snapshots with a message	Full history of who changed what and when
Merging	Combine branches back together	Everyone's work is integrated safely
Rollback	Undo changes and go back to a previous version	Mistakes are never permanent

OOP connection: Because OOP organises code into separate classes in separate files, version control works naturally. Dev A edits player.py while Dev B edits weapon.py — Git handles this with no conflicts. Without OOP, everyone might be editing the same massive file.
