How to use the falcor.keys function in falcor

export function cleanupFalcorKeys(obj) {
  if (obj === null || (typeof obj) !== 'object' || obj.cleanupFalcorKeysMetaSeen) return obj;
  const ret = {};
  // In order to handle circular objects, the key name is convoluted to make sure it's unique
  obj.cleanupFalcorKeysMetaSeen = true; // eslint-disable-line no-param-reassign
  falcor.keys(obj).forEach(key => {
    if (key === 'cleanupFalcorKeysMetaSeen') return;
    ret[key] = cleanupFalcorKeys(obj[key]);
  });
  // Cleanup to not have mutated the object
  delete obj.cleanupFalcorKeysMetaSeen; // eslint-disable-line no-param-reassign
  return ret;
}

export function falcorValues(obj) {
  return falcor.keys(obj).map(k => obj[k]);
};
