File System API vs Local Storage

Developers should learn the File System API when building web applications that require local file handling, such as photo editors, document processors, or offline-capable apps meets developers should use local storage for client-side data that needs to persist between sessions, such as user preferences, form data, or application state in single-page applications. Here's our take.
