 ## Subscribing to Events
 
 This example leverages the IOTA TypeScript SDK to subscribe to events the package with ID `<PACKAGE_ID>` emits. Each time the event fires, the code displays the response to the console.

In your TypeScript code, import `JsonRpcProvider` and a connection from the library.
