redux源码分析：enhancer

createStore 第3个参数本质是上对 createStore 方法的增强

redux 的 createStore 第3个参数

本质上是 store enhancer
常用的是 applyMiddlewares，其实我们还可以自定义其它的 enhanncer

自定义 enhancer

const ourAwesomeEnhancer = createStore => (reducer, initialState, enhancer) => {
  const store = createStore(monitoredReducer, initialState, enhancer);
  //  add enhancer logic

  return {
    ...store
    //   you can override the some store properties or add new ones
  };
};
