Would be nice to have support for keys to remove inside of (nested) arrays as well since arrays are also valid parts of a JSON object.

Example:

let data = {
    "myKey1": 123,
    "myKey2": true,
    "myKey3": {
        "myKey4": "foo",
        "myKey5": [
            {
                "myKey1": 456,
                "myKey6": null
            }
        ]
    }
};

let keyDel = require("key-del");
keyDel(data, "myKey1");

Result should be...

{
    "myKey2": true,
    "myKey3": {
        "myKey4": "foo",
        "myKey5": [
            {
                "myKey6": null
            }
        ]
    }
}

...but is...

{
    "myKey2": true,
    "myKey3": {
        "myKey4": "foo",
        "myKey5": [
            {
                "myKey1": 456,
                "myKey6": null
            }
        ]
    }
}

Hi,

I have a JSON object coming from Mongo:
{ "_id" : ObjectId("54a12e61c77c3ae01a84dba5"),
"user" : "demo",
"status" : "approved"
}
If I run:
return_obj = deleteKey(obj, fields);
where var fields = ["status"];

I get the following return_obj:
{ "_id": {
"_bsontype": "ObjectID",
"id": "U\ Ù�Þ�^��¶©�"
},
"user" : "demo"
}

I got a deep object and need to delete a prop 5 levels deep. This is apparently "not supported" yet. How come? It's just recursion?

It would be nice if we could delete keys from nested objects by their full path (in case the key is named the same in several different nested objects but you only want to delete some of them), i.e.:

var originalObject = {
one: 1,
two: 2,
three: {
nestedOne: 3,
nestedTwo: 4
},
four: {
nestedOne: 5,
nestedTwo: 6
}
}
var result = deleteKey(originalObject, ['one', 'three.nestedOne']) or like
var result = deleteKey(originalObject, ['one', '[three][nestedOne]')

While trying to delete a nested key, I am getting:

c:\node\project\node_modules\key-del\index.js:60
delete nestedObjectRef[lastAttribute];
