Explain the concept of branching in Git version control system and its main advantages.

Branching in Git is the creation of an independent line of development, allowing work on new features, fixes, or experiments without affecting the main branch (usually master or main).

Main advantages of branching:

• Isolation of changes: you can develop and test code separately.
• Parallel work: multiple developers can work on different tasks simultaneously.
• Ease of integration: after completing work, the branch is merged with the main, simplifying change management.

Example of creating and switching to a new branch:

git branch feature-xyz
git checkout feature-xyz

Or with one command:

git checkout -b feature-xyz

After completing work:

git checkout main
git merge feature-xyz

Thus, branching increases flexibility and safety in the development process.
