Branch

Summary

A lightweight, movable pointer to a line of commits — branches let you develop features, fixes and experiments in isolation from `main`. Because a branch is essentially a movable reference to a commit, creating and switching branches is lightweight and does not duplicate the entire project.

• 1Create a feature branch, make a commit, then switch back to `main`. Validate your understanding by applying it in a small practical example.
• 2Learn the difference between `git branch` and `git switch -c`. Focus on understanding the underlying reason it works, not only memorizing the definition.
• 3Practice deleting merged branches to keep your repo tidy.
