React Render Prop – Scratch that

In React, a render prop is a function prop that a component uses to know what to render. It allows a component to share its internal state with a child component, without exposing its implementation details.

Here is an example of a component using a render prop:

import * as React from "react";
class MyComponent extends React.Component {

  state = {

    count: 0,

  };
  handleClick = () => {

    this.setState({ count: this.state.count + 1 });

  };

render() { return this.props.render({ count: this.state.count, handleClick: this.handleClick, }); } }

In the example above, the MyComponent component has a state and a handleClick method. It also has a render prop that receives an object with the component’s state and handleClick method. The render prop is then used to render the component’s internal state.

To use the MyComponent component, you would pass a function as the render prop, like this:

<MyComponent

  render={({ count, handleClick }) => (

    <div>

      <p>Count: {count}</p>

      <button onClick={handleClick}>Increment</button>

    </div>

  )}

/>

In the example above, the MyComponent component is rendered using the render prop. The render prop function receives the component’s state and handleClick method as arguments, and it returns a React element that displays the component’s count and a button that can be clicked to increment the count.

Using render props can help you create more flexible and reusable components. It allows you to share state and behavior with a child component, without exposing its implementation details.
