Is it possible to somehow pass the name of the state element from the child to the parent in Raect?

Question

React

Is it possible to somehow pass the name of the state element from the child to the parent in Raect?
Parent:

class Container extends Component {
  constructor() {
    super();
    this.state = {
      test: 1
    };
    this.buyEgg = this.buyEgg.bind(this);
  }


buyEgg(value) {
    this.setState({ value: 2 });
  }

  
  render() {
    return (
      <div>
        <TestShop buyEgg={this.buyEgg} test={this.state.test} />
      </div>
    );
  }

Child:

class TestShop extends Component {
  constructor(props) {
    super();
    this.state = {
      
    };
  }

  render() {
    return (
      <div>
        <h1>{this.props.test}</h1>
        <button value="test" onClick={() => this.props.buyEgg('test')}>
          Click
        </button>
      </div>
    );
  }
}

those. we need a universal function, which is passed the name of the state element and changes to some value

Answer 1

buyEgg(value) {
    this.setState({ [value]: 2 });
  }

if I understood correctly
