Javascript clone() is not a function error

Im working on a js game, and trying to clone an object, but I keep having this error :

this[i].clone is not a function

this is my code :

Object.prototype.clone = function() {
    var i, newObj = (this instanceof Array) ? [] : {};
    for (i in this) {
        if (i === 'clone') {
            continue;
        }
        if (this[i] && typeof this[i] === "object") {
            newObj[i] = this[i].clone();
        } else {
            newObj[i] = this[i];
        }
    }
    return newObj;
};

I tried to remplace 'clone' with this solution :

JSON.parse(JSON.stringify(object)) it didn't work. any help please ?

It looks as it works

Object.prototype.clone = function() {
    var i, newObj = (this instanceof Array) ? [] : {};
    for (i in this) {
        if (i === 'clone') {
            continue;
        }
        if (this[i] && typeof this[i] === "object") {
            newObj[i] = this[i].clone();
        } else {
            newObj[i] = this[i];
        }
    }
    return newObj;
};

var person = {
    name: 'John',
    address: {
        city: 'New York'
    }
};

var clonedPerson = person.clone();

person.address.city = 'Buenos Aires';

console.log(person.address.city);
console.log(clonedPerson.address.city);

What is your call look like?
