 #  Enforces that mapDispatchToProps uses a shorthand method to wrap actions in dispatch calls whenever possible. (react-redux/mapDispatchToProps-prefer-shorthand)
 
->[mapDispatchToProps(dispatch, [ownProps]): dispatchProps] (Object or Function): If an object is passed, each function inside it is assumed to be a Redux action creator. An object with the same function names, but with every action creator wrapped into a dispatch call so they may be invoked directly, will be merged into the component’s props.
+>...`connect` supports an “object shorthand” form for the `mapDispatchToProps` argument: if you pass an object full of action creators instead of a function, `connect` will automatically call bindActionCreators for you internally. We recommend always using the “object shorthand” form of `mapDispatchToProps`, unless you have a specific reason to customize the dispatching behavior.
