Anyone else have problems with this?

Tell us what’s happening:
I Keep getting an error that target is undefined, but the component is otherwise working.

Your code so far


class ControlledInput extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      input: ''
    };
    // change code below this line
   this.handleChange =this.handleChange.bind(this);
    // 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.input} onChange = {this.handleChange} />       
        { /* change code above this line */}
        <h4>Controlled Input:</h4>
        <p>{this.state.input}</p>
      </div>
    );
  };
};

You aren’t passing event as an argument to your handler.

in addition to what @lionel-rowe said, you also have <input value={this.input} but the tests are expecting the input value to come from the state.
