Web integration - Missing a code part

Tanks for the reply !
I used this code

var twitch = $.ajax({
    type:"GET",
    url:"https://api.twitch.tv/kraken/streams?channel=kusaaa,eliszz,cystlol,valdzor,jarnulol,w_lapin?stream_type=all",
    headers:{
      'Client-ID':'ydg85xpbjqkla029haz2sspggpann2'
         },
    async: false,
    data: dataString,
    dataType: "json",
});

But the result is not what i expected. How do i render in JSON ?
I’m very new to devellopping and i don’t know how to do x) ?
