How can I use Higher-Order Components in React Native?

Higher-Order Components (HOCs) are functions that take a component and return a new component. They are used for reusing component logic.

Can you give me an example of a HOC?

Sure! A simple HOC could be one that adds loading functionality to a component. It might look like this:

const withLoading = (WrappedComponent) => {
  return class extends React.Component {
    render() {
      return this.props.isLoading ? <LoadingIndicator /> : <WrappedComponent {...this.props} />;
    }
  };
};

How do I apply this HOC to my component?

You can apply the HOC like this:

const MyComponentWithLoading = withLoading(MyComponent);

Now, MyComponentWithLoading will show a loading indicator when isLoading is true.

Are there any best practices for using HOCs?

Yes! Some best practices include naming your HOCs clearly, avoiding props collision, and ensuring they are pure functions.
