Parsing json object in javascript with an empty property name

Question

If I have the json object below... how can I access the string "Passwords must have...".

The "" property name name inside the ModelState is confusing me.

Thanks!

{
    "Message": "The request is invalid.",
    "ModelState": {
        "": [
            "Passwords must have at least one non letter or digit character. Passwords must have at least one uppercase ('A'-'Z')."
        ]
    }
}

testsome["ModelState"][""]?

var a={
    "Message": "The request is invalid.",
"ModelState": {
    "": [
        "Passwords must have at least one non letter or digit character. Passwords must have at least one uppercase ('A'-'Z')."
    ]
}
};
console.log(a.ModelState[""]);

a slight improvement: for (var i = 0; i < a.ModelState[''].length; i++) alert(a.ModelState[''][i]);

Like so

var data = {
    "Message": "The request is invalid.",
    "ModelState": {
        "": [
            "Passwords must have at least one non letter or digit character. Passwords must have at least one uppercase ('A'-'Z')."
        ]
    }
};

console.log(data.ModelState['']);

var yourAnswer = a.ModelState[""];```

You can achieve it this way:

var somedata = {
    "Message": "The request is invalid.",
    "ModelState": {
        "": [
            "Passwords must have at least one non letter or digit character. Passwords must have at least one uppercase ('A'-'Z')."
        ]
    }
};
console.log(somedata["ModelState"][""]);

var my_dict = {
    "Message": "The request is invalid.",
    "ModelState": {
        "": [
            "Passwords must have at least one non letter or digit character. Passwords must have at least one uppercase ('A'-'Z')."
        ]
    }
}
var my_string = my_dict['ModelState'][''][0]

this works for me
