Version Control


Version control is a system that records changes to a file or set of files over time so that you can recall specific versions later. (Atlassian 2025)

Version control is like a time machine for your files. It keeps track of all the changes made to your documents, code, or any other files over time. (Le Chat)

😍 Why use Version Control?

  1. Avoid Losing Work:
    • Ever accidentally deleted something important? With version control, you can easily recover previous versions of your files.
  2. Collaborate Easily:
    • Working with a team? Version control allows multiple people to work on the same project without overwriting each other’s changes.
  3. Track Changes:
    • Know exactly who made what changes and when. This is especially useful for keeping track of progress and identifying issues.
  4. Experiment Safely:
    • Want to try something new without risking your current work? Version control lets you create branches to experiment with new ideas. If it doesn’t work out, you can always go back to the original version.
