JavaScript，按特定键的值过滤对象数组

Question

我正在尝试找到使用特定键的字符串过滤对象数组的最佳方法。基本上我想要实现的是获取包含 "Type":"Blue" 的对象。这是我的数据:

[
   {
       "data": [
           {}
       ],
       "Name": "1",
       "Type": "Blue"
   },
   {
       "data": [
           {}
       ],
       "Name": "2",
       "Type": "Red"
   },
   {
       "data": [
           {}
       ],
       "Name": "3",
       "Type": "Blue"
    }
]

您可以使用filter()方法。请参阅下面的代码片段以及 MDN 中该方法的定义:

The filter() method creates a new array with all elements that pass the test implemented by the provided function.

const data = [
  {
    data: [{}],
    Name: "1",
    Type: "Blue"
  },
  {
    data: [{}],
    Name: "2",
    Type: "Red"
  },
  {
    data: [{}],
    Name: "3",
    Type: "Blue"
  }
];

const filteredData = data.filter((item) => item.Type === "Blue");
console.log(filteredData);
