如何按键值对字典数组排序

Question

我使用字典数组，在这个数组上我有很多数据。

所以，我有数组：

var array = [
{ mainCategory: "Tools", subCategory: "Some tool", id: "some code", name: "here will be some descr" },
{ mainCategory: "Tools", subCategory: "Some tool", id: "some code", name: "here will be some descr" },
{ mainCategory: "Tools", subCategory: "Some tool", id: "some code", name: "here will be some descr" },
{ mainCategory: "Tools", subCategory: "Some tool", id: "some code", name: "here will be some descr" },
{ mainCategory: "Tools", subCategory: "Some tool", id: "some code", name: "here will be some descr" },
{ mainCategory: "Tools", subCategory: "Some tool", id: "some code", name: "here will be some descr" },
{ mainCategory: "Design", subCategory: "Some Design", id: "some code", name: "here will be some descr" },
{ mainCategory: "Design", subCategory: "Some Design", id: "some code", name: "here will be some descr" },
{ mainCategory: "Design", subCategory: "Some Design", id: "some code", name: "here will be some descr" },
{ mainCategory: "Design", subCategory: "Some Design", id: "some code", name: "here will be some descr" },
{ mainCategory: "Design", subCategory: "Some Design", id: "some code", name: "here will be some descr" },
{ mainCategory: "House", subCategory: "Some House tools", id: "some code", name: "here will be some descr" },
{ mainCategory: "House", subCategory: "Some House tools", id: "some code", name: "here will be some descr" },
{ mainCategory: "House", subCategory: "Some House tools", id: "some code", name: "here will be some descr" },
{ mainCategory: "House", subCategory: "Some House tools", id: "some code", name: "here will be some descr" },
{ mainCategory: "House", subCategory: "Some House tools", id: "some code", name: "here will be some descr" },
];

如您所见，我的类别带有子类别。

所以我想过滤这个数组，例如：

如果mainCategory等于工具 或者我要查找，则我将从该数组中仅检索连接到 mainCategory 的数据。我如何过滤该数组？
