Congratulations on finishing this lesson on the react-redux library! Let’s review what you’ve learned:

• React and Redux work well together but need more to support React’s UI optimization and Redux’s one-way data flow.
• The react-redux library provides React application components access to the Redux store
• The <Provider> component wraps around the root component to give its descendants access to the - Redux store without props drilling
• Selectors are pure functions used to access all or part of the state in the Redux store
• useSelector() retrieves the application state through selectors. It must be called from within a component
• useSelector() subscribes components to data retrieved from the selectors. React, not Redux, re-renders those components when the selected data changes
• useDispatch() returns a reference to Redux store dispatch() function
