Getting Javascript Objects

Question

I am using a youtube search library

search(searchTerm, opts, function(err, results) {
           if (err) return console.log(err);

           console.dir(results);
      });

and it returns a JS Object with the first video found like this

[ { id: 'xsPHeH-pNQU',
link: 'https://www.youtube.com/watch?v=xsPHeH-pNQU',
kind: 'youtube#video',
publishedAt: '2015-04-10T19:36:16.000Z',
channelId: 'UC9EZGiMrK8-OYbLH3Yfj_QQ',
channelTitle: 'IQ Tests | Personality Tests | Funny Test Videos',
title: '✔ Which Nickname is Perfect For You? (Personality Test)',
description: 'What nickname fits you best? What is your cute nickname? What is your best nickname? What should your nickname be? Be my friend on Facebook ...',
thumbnails: { default: [Object], medium: [Object], high: [Object] } } ]

I am trying to extract the link out of this by using

var videoUrl = results.link; 

or

var videoUrl = results["link"];

but everytime I get it to log to the console what videoUrl is, it keeps saying undefined. The full code looks like this

var searchTerm = message.content.slice(8, 2000);
      search(searchTerm, opts, function(err, results) {
           if (err) return console.log(err);
           var videoUrl = results.link;
           console.dir(results);
           console.log(videoUrl);
           message.channel.send(videoUrl);
      });

Any ideas of what I'm doing wrong?

The object is in an array so you need to reference the item in the array. As it is the first item in the array you need to use [0]

var videoUrl = results[0].link;
