如何将一些对象键仅推入React JS中的另一个数组

Question

我正在从后端获取一些项目，现在我想创建单独的重复数组 ItemsModels ，并希望将这些项目发布到后端...对此有任何帮助...

从后端获取数据

  const Items = [
      { uid: "01", item: "Car", carModel: "i 20", model: 2010 },
      { uid: "02", item: "Car", carModel: "i 10", model: 2009 },
      { uid: "03", item: "Car", carModel: "Swift", model: 2011 },
      { uid: "04", item: "Car", carModel: "Polo", model: 2015 }
    ];

我想要这样的重复数组。...

 const ItemsModels = [
      { uid: "01", carModel: "Hundai i 20" },
      { uid: "02", carModel: "Hundai i 10" },
      { uid: "03", carModel: "Swift" },
      { uid: "04", carModel: "Polo" }
    ];

您可以制作一张简单的地图

const ItemsModels = Items.map(item => {
      const { uid, carModel } = item;
      return { uid, carModel };
});
