@carpben if I read your reply correctly, as far as I can see here you got enough options. Streams that have the "stream" property value of null are offline and streams that return a lot of data inside the "stream" property are online therefore giving you enough options to complete the task.

EDIT: My mistake, I looked at some wrong data. Yeah the original gist lacks offline channels, but offline channels have been added later so that the task could be completed.

how do i use this array. I am a beginner, Kindly help me . Thank you

@Ruchika30...this data is the one which is supposed to come as a successful response of our request to twitch. So, instead of using "GET" method and fetching response, we can directly store this entire thing in a variable.
If you didn't get the above part, just skip to next line.
Like var someVar = ENTIRE_ARRAY_GIVEN_HERE. Then just use someVar[0]["XYZ"] like that to access the contents of this entire array thing. Here you will need 'logo','status' and 'display_name' parameters of a stream.
