React: Create a Controlled Input Bug?

I feel as though there is a bug that causes my code to fail. I keep getting " // running tests Typing in the input element should update the state and the value of the input, and the
p
element should render this state as you type. // tests completed
I would appreciate your feedback.

  • Thank you
  constructor(props) {
    super(props);
    this.state = {
      input: ''
    };
    // change code below this line

    // change code above this line
  }
  // change code below this line
handleChange(){
  this.setState({
    input: event.target.value
  })
}
  // change code above this line
  render() {
    return (
      <div>
        { /* change code below this line */}
<input value = {this.state.input} onChange = {this.handleChange.bind(this)}
/>
        { /* change code above this line */}
        <h4>Controlled Input:</h4>
        <p>{this.state.input}</p>
      </div>
    );
  }
};

You referenced event in your handleChange method but never defined it.
