请问如何拿这个数组对象的值 组成这种结构？

Question

let good_list = [
    {
        cart_goods:[{rec_id:'123'},{rec_id:'456'}]
    },
    {
        cart_goods:[{rec_id:'789'},{rec_id:'555'}]
    }
]

想要的结果：

[
    {"cart_id":["123","456"]},
    {"cart_id":["789","555"]}
]

刚刚问的那个搞错了

谢谢大家，我自己搞出来了已经，

Answer 1

good_list.map(i => ({ cart_id: i.cart_goods.map(g => g.rec_id) }))
