bbo is a utility library of zero dependencies for javascript.

var merge = function () {
  for (var _len = arguments.length, objs = new Array(_len), _key = 0; _key < _len; _key++) {

  }

  return [].concat(objs).reduce((acc, obj) => Object.keys(obj).reduce((a, k) => {
    acc[k] = acc.hasOwnProperty(k) ? [].concat(acc[k]).concat(obj[k]) : obj[k];
    return acc;
  }, {}), {});
};
