How to get Json object name in json response [duplicate]

Question

I have the following JSON format:

Object {person: Array[10]}

I want to get the name called person.

I don't want to get the inner content just I want the name called person to store it in a variable.

How can I achieve this?

It would be clearer if you used correct terminology: person here is a "key". — user663031

According to MDN you can do this like this, assuming your object is stored in a variable named obj:

var keys = Object.keys(obj);
var person = keys[0];

Or another approach:

for ( prop in obj ) {
   // prop is the key name.
}
