我有一个对象数组，如下所示：

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"]

见上文我尝试过的。但是，我希望获得以下预期输出：["Product1", "Product2", "Product3", "Product4"]

有什么建议我做错了吗？

感谢您的答复！

最佳答案

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)
