Branching in GitHub

What is a Branch?

• A branch is a copy of the main codebase.
• Allows working on features without affecting main branch.
• Default branch is usually called main.

Creating and Using Branches

• Branches are created from main.
• Changes in branches remain isolated until merged.
• Helps in experimentation and feature development.

Commits

• A commit saves changes to the repository.
• Each commit has:
  • Unique ID
  • Commit message
• Commit messages explain why a change was made.

Pull Requests (PR)

• A pull request proposes changes from one branch to another.
• Shows differences (diffs) between branches.
• Allows review and discussion before merging.

Merging a Pull Request

• Combines branch changes into main.
• Conflicts must be resolved before merge.
• After merging, branches can be deleted safely.

Benefits of Pull Requests

• Code review
• Quality control
• Clear change history
• Team collaboration
