In Git, "staging" is the step before the commit process in your workflow. It's an intermediate area where commits can be formatted and reviewed before completing the commit.
When you use the command git add, what you're doing is staging changes for the next commit. You can think of the staging area as a sort of "buffer" between the working directory (where you are making changes) and the repository (where commits are stored).
Staging provides you with a lot of flexibility in how you commit your changes to the repository:
You can selectively stage changes. For example, if you've made changes to multiple files but you only want to commit some of those changes, you can use git add to stage only the changes in specific files.
You can stage changes incrementally. For example, if you've made a lot of changes and you want to split them into several smaller commits rather than one big commit, you can stage and commit the changes separately.
If you stage changes and then make more changes to the same files, you can use git diff to see both the changes that are staged and the changes that are not staged.
So, the staging area allows you to group and review your changes before actually committing them, which can make your history clearer and easier to understand.
