Answer 1

If you have only this file you should define *recent_tweets* function. Of cours you need to import tweets.js. For example:

<script>
    var recent_tweets = function(tweets) {
        for(var i=0; i<tweets.length; i++) {
            var tweet = tweets[i];
            var followerCounts = tweet.user.followers_count;
            var screenName = tweet.user.screen_name;
        }
    }   
</script>
<script src="tweets.js"></script>

However, there is no follower_count available.

Answer 2

This is a JSONP file, it needs to be requested via a script tag in order to execute the recent_tweets function that encloses it. Try using the jQuery ajax function.

$.ajax({
  dataType: "jsonp",
  success: function (result) {
    callback(result);
  }
});
