我要提取的是具有 2 个子数组（LocalTeam 和访问者，在本例中为 Alianza Local 和 Metapan 访问者）和每个子数组内部的另一个子数组（Substitudes）的 LineUps。
现在我需要将这些信息保存到我的应用程序中的数组中，并且通过第一部分，我能够通过此代码将本地团队和访客团队名称转换为变量，我正在使用带有 Javascript 的 React Native：
const resData = await response.json();
const equipoLocal = resData.api.fixtures[0].homeTeam.team_name;
const equipoVisitante = resData.api.fixtures[0].awayTeam.team_name;
在 resData 中得到该结果，但我认为为了获得阵容数组，我可以执行以下操作：
const lineUpLocalData = resData.api.fixtures[0].lineups.equipoLocal;
或
const lineUpLocalData = resData.api.fixtures[0].lineups.${equipolocal};
我面临的问题是，如果我采用第一种方法，API 搜索会寻找一个名为 equipoLocal 的部分，它应该是该变量的团队名称，而第二种方法给出我一个错误。
有什么想法吗？
