What is Git?

Learn the basics of Git and GitHub

Git is a distributed version control system (DVCS) used to track changes in files and coordinate work between multiple people.

What Git does:

    Keeps a complete history of every change made to your files Allows you to go back to previous versions at any time Lets multiple developers work together without overwriting each other's work makes branching easy so you can experiment without breaking the main code

Why developers use Git:

  • • Collaboration: Teams can work on the same codebase efficiently
  • • Backup: Your history is stored locally and can also be pushed to remote servers like GitHub
  • • Experimentation: Try new features safely in branches
  • • Version tracking: See exactly who changed what and when
