Code Review

This pull request refactors and simplifies the React & Redux in TypeScript guide, focusing on modern type-checking patterns for functional and class components, Redux integration, and configuration. It also introduces examples for using the @connect decorator with class components. Feedback on the changes points out that the newly added CounterWithDecorator component in docs/src/connected-class-components/with-connect-decorator.tsx should be cast to React.ComponentType<OwnProps> upon export to prevent TypeScript from requiring consumers to provide Redux-injected props.

Without casting the exported component, TypeScript will require consumers of CounterWithDecorator to provide all props (including count, onIncrement, and onDecrement which are injected by Redux). To fix this, cast the exported component to React.ComponentType<OwnProps> so that only OwnProps are required by parent components.

Suggested change

	export default CounterWithDecorator;
	export default CounterWithDecorator as React.ComponentType<OwnProps>;
