Choose the key value from a deep object structure

I'm facing a dilemma. Within the layers of this object, I need to identify and select a specific key among the nested elements. The structure of the object is as follows:

var x={
    "_shards": {
        "total": 10,
        "successful": 5,
        "failed": 0
    },
    "_all": {
        "primaries": {
            "indexing": {
                "index_total": 4,
                "index_time_in_millis": 5,
                "index_current": 0,
                "delete_total": 0,
                "delete_time_in_millis": 0,
                "delete_current": 0
            }
        },
        "total": {
            "indexing": {
                "index_total": 4,
                "index_time_in_millis": 5,
                "index_current": 0,
                "delete_total": 0,
                "delete_time_in_millis": 0,
                "delete_current": 0
            }
        }
    },
    "indices": {
        "get56_name": {
            "primaries": {
                "indexing": {
                    "index_total": 4,
                    "index_time_in_millis": 5,
                    "index_current": 0,
                    "delete_total": 0,
                    "delete_time_in_millis": 0,
                    "delete_current": 0
                }
            },
            "total": {
                "indexing": {
                    "index_total": 4,
                    "index_time_in_millis": 5,
                    "index_current": 0,
                    "delete_total": 0,
                    "delete_time_in_millis": 0,
                    "delete_current": 0
                }
            }
        }
    }
}

My question is, how do I pinpoint and extract the key "get56_name" without retrieving its value?

javascriptjson

Answer №1

Retrieve the initial key within an array of keys, such as "get56_name"

Object.keys(x["indices"])[0]

Hopefully this addresses your inquiry

Answer №2

Here's a suggestion for you:

Let my_variable = Object.keys(x.indices)[0];
