Like _.flow, but also accepts arrays of functions.

flowMap.js

function flowMap () {
  var functions = [].slice.call(arguments); // convert arguments to array
  return function () {
    var _this = this; // maintain context
    return functions.reduce(function (args, fn) {
      // for each function or array of functions,
      // pass in the previous return value.
      if (_.isArray(fn)) {
        return [fn.map(function (_fn) { return _fn.apply(_this, args); })];
      } else {
        return [fn.apply(_this, args)];
      }
    }, arguments)[0];
  };
}
