👉 Pasteboard is a type of data storage in web applications that stores and retrieves user preferences, cookies, and other information. It is commonly used to store session state, which is the temporary data stored by a browser during a user's online session. In web development, it can be used to cache frequently accessed or sensitive data for future use. Pasting this into your application allows developers to easily manage and update these preferences without requiring manual updates or changes in other parts of the codebase.
