Get nested JSON keys only

Example JSON

{
  "one": [{
    "A": {"name":"example"},
    "B": {}
  }],
  "two": [{
    "A": {"name":"booger"},
    "B": {}
  }]
}

Using this I can get keys "one" and "two" to be listed.

$.getJSON('blahblah.js', function(data){
  $.each(data, function(key){
    console.log(key);
  });
});

But using this, I can’t get "A" and "B" to be listed.

$.getJSON('blahblah.js', function(data){
  $.each(data.one, function(key){
    console.log(key);
  });
});

Why not? And how do I get those inner keys(is this the correct term?) to be listed.
Thanks

So…not sure what you’re seeing then…

var jsontext_withbrackets =
  '{"one":[{"A":{"name": "example"},"B":{}}],\
  "two":[{"A":{"name": "booger" },"B":{}}]}';

var obj1 = JSON.parse(jsontext_withbrackets);

var jsontext_withoutbrackets =
  '{"one":{"A":{"name": "example"},"B":{}},\
  "two":{"A":{"name": "booger" },"B":{}} }';

var obj2 = JSON.parse(jsontext_withoutbrackets);

console.log(obj1.one[0]);
console.log(obj2.one);
