title: How to extract an Array from API response
body: <p>Hello I am using <code>https://www.npmjs.com/package/ytfps</code> package to get the URLs and titles from youtube playlists. The format given as response to <code>ytfps(url).then(playlist =&gt;{console.log(util.inspect(playlist))}</code> is the following:</p>
  <pre><code>{
     title: 'Music Playlist',
     url: 'https://www.youtube.com/playlist?list=PLoXvI0xCls_7WZpfvrqwBNqlnZTMylyTvdo6',
     id: '7WZpfvrqwBNqlnZTMylyTvdo6',
     video_count: 16,
     view_count: 16,
     description: '',
     isUnlisted: false,
     thumbnail_url: 'https://i.ytimg.com/vi/jBmkNzfqFZUSW4/hqdefault.jpg',
     author: {
       name: 'Default',
       url: 'https://www.youtube.com/user/gadfgagaq',
       avatar_url: 'https://yt3.ggpht.com/ytc/AKedOLQoEJLXJMV2t3MRgadfqNuhWk46GwnYr7r1DAgnGbsQ=s176-c-k-c0x00ffffff-no-rj'
     },
     videos: [
       {
         title: 'Barei - Say Yay! (Eurovision 2016 Spain)',
         url: 'https://www.youtube.com/watch?v=jBmkNzFZUW4',
         id: 'jBmkNzFZUW4',
         length: '3:07',
         milis_length: 187000,
         thumbnail_url: 'https://i.ytimg.com/vi/jBmkNzFZUW4/hqdefault.jpg',
         author: [Object]
       },
       {
         title: 'Sound of Silence',
         url: 'https://www.youtube.com/watch?v=4S6sT_2gM2o',
         id: '4S6sT_2gM2o',
         length: '3:16',
         milis_length: 196000,
         thumbnail_url: 'https://i.ytimg.com/vi/4S6sT_2gM2o/hqdefault.jpg',
         author: [Object]
       },
  
     ]
  }
  </code></pre>
  <p><strong>What I want</strong> is to get  2 arrays one of URLs and the other one of titles, like this:</p>
  <pre><code>url= [https://www.youtube.com/watch?v=jBmkNzFZUW4', 'https://www.youtube.com/watch?v=4S6sT_2gM2o', and so on... ]
  titles =['Barei - Say Yay! (Eurovision 2016 Spain)', 'Sound of Silence', and so on ]
  </code></pre>
  <p>So what is the best way to extract those 2 arrays?</p>
