What is the purpose of a Git Checkout?

The purpose of Git Checkout is to switch to a specific branch within a Git repository. When you use the checkout command, you're essentially telling Git to update the working directory to reflect the state of the specified branch. This means that all files will be updated to match those in the branch you are switching to. This is crucial for developers who may need to move between different branches to work on various features, bug fixes, or versions of the project.

Switching branches allows developers to isolate their changes and ensures that they can work in a clean environment without interfering with the work on other branches. This functionality is fundamental to the branching model that Git supports, enabling collaborative work on projects.

While deleting a branch, adding changes, and pushing changes to a remote repository are important Git operations, they do not relate directly to the specific functionality of the checkout command.
