Turns an object whose values are action creators, into an object with the * same keys, but with every function wrapped into a `dispatch` call so they * may be invoked directly. This is just a convenience method, as you can call * `store.dispatch(MyActionCreators.doSomething())` yourself just fine. 以上是一段源码的注释，意思是我们不需要使用dispatch了,，调用bindActionCreators后返回的action就可以了，返回action集合对象中所有action方法都被包了一层dispatch

function bindActionCreator(actionCreator, dispatch) {  return (...args) => dispatch(actionCreator(...args))}

　　这里是关键源码，就是帮你包了一层dispatch。一般配合

mapDispatchToProps把action传到props里面，然后直接this.props.someAction(someArgs)就等同于，你dispatch(someAction(someArgs)); 欢迎讨论，如果不正，劳请指出
