我有两个 CSV 文件:
球数据.json
    [
      {
        "id": "1",
        "color": "red",
      },
      {
        "id": "2",
        "color": "blue",
      }]
法院.json:
    [
      {
        "court_id": 2001,
        "ball_in_use": "1",
      },
      {
        "court_id": 2005,
        "ball_in_use": "2",
      }]
如何根据球场 ID 映射球的颜色?例如:2001 --> 红色,2005 --> 蓝色
我尝试了以下方法
    const App = (props) =>{
        let color = balldata.map((c, index) => {
          return c.id + "-" + c.color;})
        let game = courtdata.map((ball, index) => {
          return ball.ball_in_use;})
        return(
          //not sure what to return here since I am unable to use {color} or {game}
    )}
