Removing Data from localStorage
index.js
When you work with localStorage, you may need to delete data that is no longer needed. The removeItem method allows you to remove a single item by its key. For example, if you previously stored a value with the key "user", calling localStorage.removeItem('user') will delete only that entry, leaving the rest of the stored data untouched.
If you want to delete all data saved in localStorage, use the clear method. This method removes every key-value pair stored in localStorage, returning it to an empty state. Use clear with caution, as it cannot be undone and will erase all stored data for your web application.
