JSON reference 'name' not 'value'

[RMWChaos]

Okay, this should be simple, but my simple little brain just can't quite figure it out.

If I have a JSON object like this:

var myJSONArray(arrayName)
   {
   "name1"  :  "value1",
   "name2"  :  "value2
   };
 

I know how to reference the values: arrayName.value1, arrayName.value2. I can even iterate over the values: for (var idx in arrayName), and reference all the values: arrayName[idx].

Now how in the world do I reference the names when I don't know them? I have been looking everywhere for this answer. Say I want a simple output of "name1 is value1" and "name2 is value2"...it would be something like: arrayName[something?] + " is " + arrayName[index].

Thanks.

I was able to get my answer in this thread:

Basically, if...

for(var index in object)
 

...then "index" is the name and "object[index]" is the value.
