🔄 Version Control. Git

What Is Version Control?

Version control is the process of tracking and managing changes to code. It’s especially important for teamwork, when multiple developers are making edits to the same project.

Why is it important?

• ✅ Allows you to roll back to a previous version of the code
• ✅ Helps track changes and their authors
• ✅ Makes collaborative development easier

Git – The Main Version Control Tool

Git is the most popular distributed version control system (VCS). It’s used by developers around the world and powers platforms like GitHub, GitLab, and Bitbucket.

🔹 Core Git Concepts

1. Local and Remote Repositories

   • Git stores all changes in a local repository on your machine.
   • The repository can be synchronized with a remote server, such as GitHub.

2. Commits and Change History

   • A commit is a saved snapshot of changes in the project history.
   • Each commit has a unique hash (identifier) to easily track edits.

3. Branching and Merging

   • Git allows you to create branches to work on new features without breaking the main code.
   • Once finished, the branch can be merged into the main one.

4. Conflict Resolution

   • If two developers modify the same file, a conflict may occur.
   • Git allows you to manually choose which changes to keep.

5. Team Collaboration

   • Developers make changes in their own branches.
   • After review, changes are merged into the main branch.
   • This prevents chaos and improves quality control.

Why Is Git Better Than Just Copying Files?

Conclusion

Git is a powerful tool for managing code versions. If you’re developing software, learning Git is a must-have skill!
