Why Use Git?

Understand what version control is and why Git is essential for every developer.

Welcome to the Git & GitHub tutorial series! Git is the most popular version control system in the world, and GitHub is the largest platform for hosting and collaborating on code.

What is Version Control?

Version control is a system that records changes to files over time so you can recall specific versions later. Think of it as an unlimited undo button for your entire project.

Why Use Git?

  • Track changes — see exactly what changed, when, and who changed it
  • Undo mistakes — revert to any previous version of your code
  • Collaboration — multiple developers can work on the same project simultaneously
  • Branching — experiment with new features without affecting the main code
  • Backup — your code history is stored safely
  • Industry standard — virtually every company uses Git

Without Git

Without version control, developers often resort to:

  • Saving files as project_v1, project_v2, project_final, project_final_FINAL
  • Emailing code back and forth
  • Manually merging changes from multiple people
  • No way to undo mistakes beyond Ctrl+Z

  • Installing and configuring Git
  • Creating repositories and making commits
  • Branching and merging
  • Using GitHub for collaboration
