javascript forEach 对数组/json 数据但按最新日期排序？

Question

是否可以修改以下内容，以便在 foreach 上它会反转，以便数据的最新日期排在第一位，而不是从最旧到最新？

Answer 1

不适用于普通的forEach。可能性:

• 假设按升序排列。从 length - 1 到 0 循环索引。非破坏性。
• 假设按升序排列。应用reverse，然后应用forEach。具有破坏性。
• 假设它是未排序的。对数组进行排序，然后应用 forEach。具有破坏性。
• 假设它是未排序的。创建索引数组，按数组中相应的值对索引进行排序，对索引应用 forEach 并访问数组成员。非破坏性。
• 假设它是未排序的。使用 slice 克隆数组，然后应用 sort 和 forEach。非破坏性。
