How to access an array in a JSON object?

Question

I have the following JSON object:

[
    {
        "comments": [
            {
                "created_at": "2011-02-09T14:42:42-08:0         


        

Answer 1

The object being returned is itself an array, so to get to the first comment (as an example), this is how you would access it:

dataJS[0].comments[0]
