javascript - 展平对象数组(键/值对)

Question

我有一个如下所示的对象数组:

let data = [{
  name: "Product1",
  category: "category 1"
}, {
  name: "Product2",
  category: "category 2"
}, {
  name: "Product3",
  category: "category 3"
}, {
  name: "Product4",
  category: "category 4"
}]

var flattened = [].concat.apply([], data);

console.log(flattened)

// expected output:
// ["Product1", "Product2", "Product3", "Product4"]

请参阅上面我尝试过的内容。但是，我希望得到以下预期输出:["Product1", "Product2", "Product3", "Product4"]

有什么建议我做错了什么吗？

感谢您的回复!

Answer 1

为什么不只是简单的 map

let data = [{name: "Product1",category: "category 1"}, {name: "Product2",category: "category 2"}, {name: "Product3",category: "category 3"}, {name: "Product4",category: "category 4"}]

var flattened = data.map(({ name }) => name)

console.log(flattened)
