Hooks are the modern way to interface with Redux. They replace the complex legacy patterns and make your code cleaner and more intuitive.
1From Connect to Hooks
Before React 16.8, connecting a component to Redux required the connect() Higher-Order Component. It was powerful but verbose, involving mapStateToProps and mapDispatchToProps. Redux Hooks provide the same power with much less code. They allow you to 'reach into' the store directly from within your functional component's logic, keeping everything in one place.
2Granular Selection
One of the best things about useSelector is its ability to perform 'granular selection'. Instead of getting the entire state object, you pick only the specific properties your component needs. This is critical for performance; your component will *only* re-render if the specific data you selected changes, even if other parts of the store are updating.
