如何在react中实现难解映射

import React, { Component } from 'react';

class MyComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      mapping: {
        'difficultValue1': 'easyValue1',
        'difficultValue2': 'easyValue2',
        // 添加更多映射关系
      },
      difficultValue: 'difficultValue1'
    };
  }

  handleChange = (event) => {
    this.setState({ difficultValue: event.target.value });
  }

  render() {
    const { mapping, difficultValue } = this.state;
    const easyValue = mapping[difficultValue];

    return (
      <div>
        <select value={difficultValue} onChange={this.handleChange}>
          <option value="difficultValue1">Difficult Value 1</option>
          <option value="difficultValue2">Difficult Value 2</option>
          {/* 添加更多选项 */}
        </select>
        <p>Easy Value: {easyValue}</p>
      </div>
    );
  }
}

export default MyComponent;
