event.preventDefault() is a method often used in plain js too ^^ It’s used to prevent the default behaviour of something ( as the name suggests ^^)

this.setState is strictly related to the react component - it’s used to change the state of the component, and in this specific case

should […] sets the component state property submit to the current input value

The event.preventDefault should be used before to change the state in your handleSubmit^^

Good luck!

Sorry but I can’t understand what to do

Sorry I didn’t get that. Can you please explain it in a better manner

As the randelldawson says.

You must call the eventDefault() in the handleSubmit(event) function.

Look into my code :

 handleSubmit(event) {
    // change code below this line
        event.preventDefault()
         this.setState({
        submit:this.state.input     
      })
