Using Run Function widget in Studio

// Description
// This Function showcases how you can send information into your Twilio Function
// From Twilio Studio's Run Function Widget and respond back with JSON.
// Twilio Studio will parse the returned JSON and incorporate it into your flow.

// Note: The Studio Run Function Widget provides additional flexability over the HTTP Request
// Widget but either  can be used to communicate with external API's.

exports.handler = function (context, event, callback) {
  // Function Parameters Sent in from Studio Run Function Widget are accessible from the
  // Function event object, for example event.key would provide the value you sent in for
  // the key called key. In our example, our Run Function widget is sending in the From
  // Key: From, Value: {{trigger.message.From}} (which sends in the From Telephone Number)

  let from = event.From;

  let randomQuotes = ['Good', 'Day', 'Dachshund', 'Winston'];
  console.log(randomQuotes.length);
  let randomArrayIndex = Math.floor(Math.random() * randomQuotes.length);
  console.log(randomArrayIndex);

  // We send the results back into our Studio flow as an object so the respective
  // Studio Send Message or Say/Play widget can respond with the results.

  return callback(null, {
    quote: randomQuotes[randomArrayIndex],
    from: from,
  });
