Could you explain what a branch in the Git version control system is?

A branch in Git is a pointer to a specific commit that allows parallel development of different versions of a project. Essentially, a branch is a separate line of development where changes can be made without affecting the main line (usually the master or main branch).

When you create a branch, Git simply creates a new pointer that can be moved forward as new commits are added. This makes it easy to switch between different tasks, experiment, and then merge changes back.

Example of creating and switching to a branch:

git branch feature
git checkout feature

Or with a single command:

git checkout -b feature
