function withClickCount(Component) {
return class extends React.Component {
constructor(props) {
super(props);
this.state = { count: 0 };
this.handleClick = this.handleClick.bind(this);
}
handleClick() {
this.setState({ count: this.state.count + 1 });
}
render() {
return (
);
}
};
}In this example, the withClickCount function takes a component as an argument and returns a new component that adds a count and onClick prop to the original component. The new component keeps track of how many times it has been clicked and passes that information down to the original component.
To use this higher-order component, you can wrap any component with it like this:
const MyComponentWithClickCount = withClickCount(MyComponent);
Now, MyComponentWithClickCount has the count and onClick props added to it, and can be used like any other component.
HOCs can be a powerful tool for creating reusable and composable components in React. However, it’s important to use them sparingly and to make sure that they don’t become too complex or difficult to understand.
