所以我現在被一個 JavaScript 任務困住了幾個小時。
所以我得到了一個包含以下資料的 Json 檔案：
{
"owner": "Jun31d",
"info": [{ "id": 1, "name": "bob", "flavour": "vanilla", "age": 43 },
{ "id": 2, "name": "Juneid", "flavour": "Chocolate", "age": 19 },
{ "id": 3, "name": "Patrick", "flavour": "Strawberry", "age": 25 },
{ "id": 4, "name": "Jean", "flavour": "Mint", "age": 31 },
{ "id": 5, "name": "Ahmad", "flavour": "vanilla", "age": 18 },
{ "id": 6, "name": "Ali", "flavour": "Bubblegum", "age": 19 },
{ "id": 7, "name": "Frank", "flavour": "Pistachio", "age": 23 }
]
}
我的分配說明如下：
操作說明
因此，根據我的理解，我需要創建一個包含兩個字串引數的函式，并且需要將位于陣列中的物件內部的屬性更改為新屬性。
直到現在繼承人我所做的：
'use strict'
const iceCream = require('./main.json')
let namespace = {
changeProp : function (newprop,oldprop) {
for (let oldprop in iceCream.info) {
}
}
}
我知道這并不多，但我只是想要一些幫助，以了解我如何在我的分配上更進一步。
任何幫助表示贊賞，謝謝

您可以輕松地更換oldKey與newKey使用地圖，Object.keys，并減少

這就是你可以做到的。簡單，簡單和討厭的解決方案。
