-```javascript

-const path = require('path')

 This helper function does the following: It establishes a WebSocket connection to the XRP Ledger, calls the XRP Ledger API's [ledger method](../../../references/http-websocket-apis/public-api-methods/ledger-methods/ledger.md) and returns the ledger index from the response. We will wire up this function at the end of this step.
