Why we use git checkout command in git?

In Git, the git checkout command is used to switch between different branches or to restore files to their previous state. Here are some use cases of the git checkout command:

Switching between branches:

If you have multiple branches in your Git repository and you want to switch to a different branch, you can use the git checkout command followed by the name of the branch you want to switch to. For example:

git checkout feature-branch

This command will switch your working directory to the feature-branch branch.

Creating a new branch:

You can create a new branch in Git and switch to that branch in a single command using the git checkout command followed by the -b option and the name of the new branch. For example:

git checkout -b new-feature-branch

This command will create a new branch called new-feature-branch and switch your working directory to that branch.

Restoring files to a previous state:

If you have made changes to a file in your Git repository and you want to restore the file to its previous state, you can use the git checkout command followed by the name of the file. For example:

git checkout myfile.txt

This command will restore the myfile.txt file to the version that is currently committed in Git.

Overall, the git checkout command is a versatile command that is used for many different purposes in Git, including switching between branches, creating new branches, and restoring files to previous states.
