I just started looking into this and require some help to start off

Thanks, I didn’t know that was possible.
Let’s say I use this call:

$.getJSON('https://api.twitch.tv/kraken/streams?channel=herpaderpus,turtles_head,nubstep_rs,taketv,destiny,followgrubby&callback=?’, function(d) {
});

How would I have to get all the data from this collection? How can I iterate over each member? How do I get data from this call at all? I’ve tried the following (without success, sadly):

if (d.followgrubby.stream != null)
{
alert(“Working!”)
}

(of course I made sure he was actually streaming)

Also, I believe I forgot a good amount of ; at the end of functions in my first draft, I fixed those too and it solved my 2nd issue from earlier
