# Working With the JS SDK

TD JavaScript SDK (TD JS SDK) allows Treasure Data to store first-party cookies on your domain’s website and to track your website’s users across the other platforms and collect information. By using the TD JS SDK, you don’t have to install anything server-side to track website activities.
