What's the main difference between mapStateToProps and mapDispatchToProps in React-Redux bindings?
- mapStateToProps maps state from the Redux store to component props.
- mapDispatchToProps maps actions to component props.
- mapStateToProps maps actions to component props.
- mapDispatchToProps maps state from the Redux store to component props.
The main difference between mapStateToProps and mapDispatchToProps is that mapStateToProps is used to map state from the Redux store to component props, whereas mapDispatchToProps is used to map actions to component props. mapStateToProps allows you to access and use Redux state in your component, making it available as props. mapDispatchToProps, on the other hand, allows you to dispatch Redux actions from your component, making action creators available as props. The other options provide incorrect definitions of these functions.
