An opinionated lib to create actions and reducers for Redux

    return action.payload;

export const logger = {};

for (const level in console) {
  if (typeof console[level] === 'function') {
    logger[level] = function levelFn(...args) {
      const lastArg = args.pop();

      if (Array.isArray(lastArg) && lastArg.type === batchType) {
        lastArg.forEach(action => {
          console[level].apply(console, [...args, action]);
        });
