Question

What are the different ways to write mapDispatchToProps()?

Answer 1

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.
