Flatten JSON objects

flatten-example.js

var flatten, obj;

flatten = require ('./flatten');
obj = {
  foo: 'bar',
  bar: 'foo',
  foobar: {
    foo: 'foo',
    bar: 'bar'

console.log(flatten(obj));

/* RESULT:

      'bar': 'foo',
      'foobar.foo': 'foo',
      'foobar.bar': 'bar'

flatten.js

var flatten;

flatten = module.exports = function(obj, path, result) {
  var key, val, _path;
  path = path || [];
  result = result || {};
  for (key in obj) {
    val = obj[key];
    _path = path.concat([key]);
    if (val instanceof Object) {
      flatten(val, _path, result);
