Clones an object and returns the clone.

cloneObject.js

// recursive function to clone an object. If a non object parameter
// is passed in, that parameter is returned and no recursion occurs.

function cloneObject(obj) {
    if (obj === null || typeof obj !== 'object') {
        return obj;
    }

    var temp = obj.constructor(); // give temp the original obj's constructor
    for (var key in obj) {
        temp[key] = cloneObject(obj[key]);
    }

    return temp;
}

var bob = {
    name: "Bob",
    age: 32
};

var bill = (cloneObject(bob));
bill.name = "Bill";

console.log(bob);
console.log(bill);
