What is the purpose of the [i] in the for loop : <p>I have some line of code that I don't fully understand. I am looking through objects in an api and was wondering what is the purpose of the [i] in d2.follows[i].user.display_name if the code is:</p>

<pre><code>$.getJSON(followerURL, function(d2){
  for(var i=0; i&lt;d2.follows.length; i++){
    var displayName = d2.follows[i].user.display_name;
 following.push(displayName);
</code></pre>

<p>I'm searching through object to find the number of followers a channel has.  is  <a href="https://i.stack.imgur.com/PZUuB.png" rel="nofollow noreferrer">Here is an image of the object</a> I would greatly appreciate an explanation of this block of code.</p>
