Why do we need a LocalStorage viewer? Applications in Web Development

LocalStorage is a Web Storage API that allows storing key-value data on the user's browser, persisting across sessions (not lost when closing the browser). This is a common way to save user preferences, authentication tokens, cached data, form drafts, shopping carts... When developing and debugging web applications, you often need to: View the data being saved in localStorage. Check if format and value are correct. Add/edit data to test different scenarios. Delete data to reset state. Clear all to test fresh user experience. Although the DevTools browser has a localStorage viewer, this tool provides a more user-friendly interface with features such as search, inline editing, display size, and one-click copy.
