Delete the key which contains empty object inside an array using javascript or jQuery

Question

I want to delete the JSON key which contains empty object inside an array...
This is my JSON structure:

{
    "CreateSubnet": {
        "description": "Creatingasubnet.",
        "input": {
            "body": {
                "subnet": {
                    "network_id": "sdfsdfds",
                    "ip_version": "sdfdsfs",
                    "cidr": "sdfsdf",
                    "allocation_pools": [
                        {}
                    ]
                }
            }
        },
        "action": "neutron.create_network",
        "publish": {},
        "on-success": []
    }
}

Please help me to delete the element "allocation_pools"..
I never want this key and this value ...

The expected output JSON will be look like...

{
    "CreateSubnet": {
        "description": "Creatingasubnet.",
        "input": {
            "body": {
                "subnet": {
                    "network_id": "sdfsdfds",
                    "ip_version": "sdfdsfs",
                    "cidr": "sdfsdf"
                }
            }
        },
        "action": "neutron.create_network",
        "publish": {},
        "on-success": []
    }
}

Note this JSON is from external source it changes dynamically...
So please tell me how to validate the JSON key contains Array...
if yes , Check whether it has empty object or not ....
This is my question

Use the delete operator to remove the property.

var obj = {
    "CreateSubnet": {
        "description": "Creatingasubnet.",
        "input": {
            "body": {
                "subnet": {
                    "network_id": "sdfsdfds",
                    "ip_version": "sdfdsfs",
                    "cidr": "sdfsdf",
                    "allocation_pools": [
                        {}
                    ]
                }
            }
        },
        "action": "neutron.create_network",
        "publish": {},
        "on-success": []
    }
}
delete (obj.CreateSubnet.input.body.subnet.allocation_pools);
document.getElementById("output").innerHTML = JSON.stringify(obj)

<div id="output"></div>
