How to use the @azure/event-hubs.EventHubProducerClient function in @azure/event-hubs

export async function main(): Promise {
  console.log(`Running sendEvents sample`);

  const producer = new EventHubProducerClient(connectionString, eventHubName);

  console.log("Creating and sending a batch of events...");

  const eventsToSend = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10"];

  try {
    // By not specifying a partition ID or a partition key we allow the server to choose
    // which partition will accept this message.
    //
    // This pattern works well if the consumers of your events do not have any particular
    // requirements about the ordering of batches against other batches or if you don't care 
    // which messages are assigned to which partition.
    //
    // If you would like more control you can pass either a `partitionKey` or a `partitionId`
    // into the createBatch() `options` parameter which will allow you full control over the 
    // destination.
