 * [`mapStateToProps(state, [ownProps]): stateProps`] \(*Function*): If specified, the component will subscribe to Redux store updates. Any time it updates, `mapStateToProps` will be called. Its result must be a plain object, and it will be merged into the component’s props. If you omit it, the component will not be subscribed to the Redux store. If `ownProps` is specified as a second argument then `mapStateToProps` will be re-invoked whenever the component receives new props.
 
-* [`mapDispatchToProps(dispatch, [ownProps]): dispatchProps`] \(*Object* or *Function*): If an object is passed, each function inside it will be assumed to be a Redux action creator. An object with the same function names, but bound to a Redux store, will be merged into the component’s props. If a function is passed, it will be given `dispatch`. It’s up to you to return an object that somehow uses `dispatch` to bind action creators in your own way. (Tip: you may use [`bindActionCreators()`](http://gaearon.github.io/redux/docs/api/bindActionCreators.html) helper from Redux.) If you omit it, the default implementation just injects `dispatch` into your component’s props.

+In short,
 
 * Reducers should never mutate state, they must return new objects, or React Redux won’t see the updates.
 * Make sure you either bind action creators with `mapDispatchToState` argument to `connect()` or with `bindActionCreators()` method, or that you manually call `dispatch()`. Just calling your `MyActionCreators.addTodo()` function won’t work because it just *returns* an action, but not *dispatches* it.
