incrementCount() {
  this.setState((state) => {
    // Important: read `state` instead of `this.state` when updating.
    return {count: state.count + 1}
  });
}

handleSomething() {
  // Let's say `this.state.count` starts at 0.
  this.incrementCount();

  this.incrementCount();

  // If you read `this.state.count` now, it would still be 0.
  // But when React re-renders the component, it will be 3.
