What is one use of local storage in client-side scripting?

Local storage in client-side scripting is primarily used to save user data, which can include information similar to cookies but with a more extensive capacity and longer retention. Local storage enables web applications to store data on the user's device in a key-value format. This data persists even after the browser is closed and reopened, allowing for a more seamless experience by retaining user preferences, settings, or any necessary application state between sessions.

This mechanism is particularly useful for enhancing user experience by remembering user inputs or storing application data that does not need to be sent back to the server on every request. While it can accomplish some goals similar to cookies, local storage offers greater storage limits and simplicity for specific use cases, such as small application state management without involving server interactions.

The other options do not accurately describe the direct utility of local storage in client-side scripting. Storing system files is beyond the scope of local storage, which is intended for web applications and not for operating system files. Creating interactive web pages can involve local storage, but it's not the primary use case for it; rather, many technologies (like JavaScript) contribute to interactivity. Finally, while reduced server load is a benefit of using local storage, it is a broader consequence of client-side storage rather than
