Cookie Examples

Client-side cookie storage is a convenient way to store small pieces of data on the user's browser. This data persists even after the user closes the browser window, making it useful for various purposes such as session management, user preferences, and tracking. In this documentation we will show you examples on how you can use client-side cookie storage.
