class App extends Component {
  constructor() {
    super();
    this.state = {
      body: 'This is body'
    };
   
    this.handleChange = this.handleChange.bind(this);
    this.handleSubmit = this.handleSubmit.bind(this);
  }
   
  handleChange(event) {
    this.setState({body: event.target.value});
  }
   
  handleSubmit(event) {
    console.log(this.state);
    event.preventDefault();
  }
   
  render() {
    return (
      <div>
        <h1>React Textarea onChange Example - HDTuto.com</h1>

          <strong>Body:</strong>
           
          <textarea 
              value={this.state.body} 
              onChange={this.handleChange} />
            
          <input type="submit" value="Submit" />
        </form>
      </div>
    );
  }
}
  
render(<App />, document.getElementById('root'));

Output:
