Need a little help $.forEach

I need a little help http://codepen.io/tushar_13/full/pydvON/

Now i have to loop through my array Twitchers

but when I want to append the data to the html body, it is looping inside the same list look at my codepen, you;ll see what I am talking about.

So now the problem is I have to loop through to provide a url to get the json data, so what should I do so that each channel displays on the separate line?

<div class="container">
  <button class="btn">All</button>
  <button class="btn">Online</button>
  <button class="btn">Offline</button>
<ul id="result"></ul>
</div> 
$(document).ready(function () {

var twitchers = ["freecodecamp", "brunofin", "MEDRYBW", "storbeck", "terakilobyte", "habathcx","RobotCaleb","thomasballinger","noobs2ninjas","beohoff"];
 var name;
 var status;
 var logo;

  twitchers.forEach(function(user) {
var channelUrl ="https://api.twitch.tv/kraken/channels/"+user+ '?callback=?';
var streamUrl = "https://api.twitch.tv/kraken/streams/"+ user+'?callback=?';

    $.getJSON(channelUrl, function(channel) {
      $.getJSON(streamUrl ,function(stream) {
        if(stream.stream == null) {
          status = '<i class="fa fa-ban"></i>'+ ' Offline';
        } else {
          status = '<i class="fa fa-check"></i>'+ ' Online';
        }
        name = channel.display_name;


        if (channel.logo == null) {
          channel.logo = 'http://www.trickyladygaming.com/wp-content/uploads/2015/10/Twitch-Icon-150x150.png'
        } else {
        logo = '<img src="'+channel.logo+'" id="logo">'
        }
        var html = '<div id="main-section">';
        html+= '<li><a href="https://www.twitch.tv/'+user+'" target="_blank">'+name+'</a>';
    html += logo;
        html += status;
        html += '</li></div>'
   $("#result").html(html);




      })// end streams json
    })// end channels json
  });// end each
}); // end ready

You are replacing the the entire contents of the result each time in the loop with this line:

        $("#result").html(html);

What you probably want is more like:

        $(html).appendTo("#result");

This would add to the list. You've got a bit of other work to do yet (like you probably don't want to wrap your li's in div's), but that should get you going.
