What is Git Reset?

Git reset is a command in the Git version control system used to reset the current state of the repository to a specified point. It allows you to undo changes, unstage files, and move the HEAD pointer to a different commit or branch. There are three main options for git reset: --soft, --mixed, and --hard. The --soft option preserves changes in the working directory and staging area, --mixed resets the staging area to match the specified commit, and --hard discards all changes in both the staging area and the working directory. Git reset can be dangerous, especially when using the --hard option, as it permanently discards uncommitted changes. The git checkout -- command is used to restore a specific file to its state as it existed in a particular commit, which is helpful when you want to revert changes made to a file back to a previous state without affecting other files in your working directory.
