Can you explain the concept of using branches in the Git version control system?

Branches in Git allow parallel development of different features, fixes, or experiments without affecting the main (usually master or main) branch. Each branch is a separate line of commit history.

Main points:

• A branch is created as a pointer to a specific commit.
• Changes in one branch do not affect others until a merge occurs.
• They help isolate work on tasks, simplifying collaboration and code management.

Example usage:

git checkout -b feature-branch  # Create and switch to a new branch
# Work, make commits

git checkout main                # Return to the main branch

git merge feature-branch        # Merge changes from feature-branch into main

Thus, branches help organize the development process, minimize conflicts, and maintain the stability of the main code.
