Git stash is a powerful feature of the Git version control system which allows you to store changes that you make to a project in isolation from your main branch. This can be useful when you need to make a change to the project but don’t want to commit it just yet, or if you need to move from one task to another without losing the changes you’ve made so far.
The way git stash works is by adding the changes you’ve made to the git index (the staging area), then stashing them away so they can be retrieved later. This is done with the command “git stash”.
When you run the git stash command, git stores the changes you’ve made as a “stash”, or a collection of changes that can be easily recalled later. It also creates a new commit, with a message indicating the stash was created.
When you’re ready to restore the changes you stashed away, all you need to do is run the command “git stash pop”. This will restore the changes back to the state they were in when you stashed them away. It also removes the commit that was created when you stashed the changes, so it’s like the stash never existed.
Git stash is an incredibly useful tool for anyone working with version control systems. It allows you to isolate changes for review and testing, before committing them to the main branch. And if you ever need to discard your changes, the “git stash pop” command will remove them and restore the project to its original state.
