Version Control

Version control is a system that tracks every change made to a set of files, who made it and why, so you can compare versions, restore earlier ones and let many people work on the same project safely. Git is by far the most widely used system today.

Why it matters

Without version control, teams email zip files and overwrite each other's work. With it, each change is a recorded step, so you can find which change introduced a bug, undo it, or experiment on a branch without risking the working version. It is also the foundation of code review और CI/CD.

Example

$ git log --oneline
a1b2c3d Fix login redirect loop
9f8e7d6 Add password reset email
4c5b6a7 Initial commit

Each line is a saved snapshot. If the redirect fix causes trouble, you can revert that one commit and keep the rest.

Common mistakes

• Committing passwords, API keys or large binary files, which stay in history even after deletion.
• Treating version control as a backup; unpushed work on one laptop is not backed up.
• Making huge, unrelated changes in one snapshot, which makes history hard to read.
