what is wrong with my code

Your code so far


class MyComponent extends React.Component {
  constructor(props) {
    super(props);
    this.state = {
      display: true
    }
    this.toggleDisplay = this.toggleDisplay.bind(this);
  }
  toggleDisplay() {
    this.setState({
      display: !this.state.display
    });
  }
  render() {
    // change code below this line
    {this.state.display   &&  <h1>Displayed!</h1>}
    return (
       <div>
         <button onClick={this.toggleDisplay}>Toggle Display</button>
         <h1>Displayed!</h1>
       </div>
    );
  }
};

@Hamzah98, there’s an h1 element in the code already. Do you mean for there to be two h1 elements?

3

i mean to type the conditional that if display is true then h1 should display

4

@Hamzah98 Consider replacing the existing h1 instead of creating a new one.

Another aproach could be, assing a new variable with ternary conditional and that variable used into the render()

Something like this :wink:

const superpan = this.state.display ? '<p>Help me superpan!</p>' : null;

Finally, you are able to use this variable with braces into the return() jsx :eyes:

<div>
{superpan}
</div>
