Version control tracks every change made to a codebase over time, recording who changed what and when.
The Problem It Solves
Without it, teams resort to naming files "final_v2_reallyfinal.php" — version control replaces that chaos with a complete, searchable history and the ability to safely undo any change.
Why Git Specifically
Git is the dominant version control system because it works offline, handles branching (parallel versions of code) efficiently, and pairs with platforms like GitHub for team collaboration.
