import React from 'react';
import Textarea from './Textarea';

class ParentComponent extends React.Component {
  render() {
    return (
      <div>
        <Textarea value={this.props.children} />
      </div>
    );
  }
}

export default ParentComponent;

import React from 'react';

class Textarea extends React.Component {
  render() {
    return (
      <textarea value={this.props.value} />
    );
  }
}

export default Textarea;
