Small change to React solution to follow best practice

JavaScript
1

Tell us what’s happening:

The solution doesn’t seem to follow best practice around updating state variables (from this lesson: https://www.freecodecamp.org/learn/front-end-libraries/react/use-state-to-toggle-an-element)

The setState function should take a state argument and update state.counter, rather than update this.state.counter.

Your code so far


class Results extends React.Component {
constructor(props) {
  super(props);
}
render() {
  return (
    <h1>
    {
      this.props.fiftyFifty ? 'You Win!' : 'You Lose!'
    }
    </h1>
  )
};
};

class GameOfChance extends React.Component {
constructor(props) {
  super(props);
  this.state = {
    counter: 1
  }
  this.handleClick = this.handleClick.bind(this);
}
handleClick() {
  this.setState((state) => ({
    counter: state.counter + 1
  }));
}
render() {
  const expression = Math.random() >= .5;
  return (
    <div>
      <button onClick={this.handleClick}>Play Again</button>
      { /* change code below this line */ }
      <Results fiftyFifty={expression}/>
      { /* change code above this line */ }
      <p>{'Turn: ' + this.state.counter}</p>
    </div>
  );
}
};
