What are the different ways to write `mapDispatchToProps()`?

There are a few ways of binding action creators to dispatch() in mapDispatchToProps().

Below are the possible options:

const mapDispatchToProps = (dispatch) => ({
  action: () => dispatch(action()),
});

const mapDispatchToProps = (dispatch) => ({
  action: bindActionCreators(action, dispatch),
});

const mapDispatchToProps = { action };

The third option is just a shorthand for the first one.
