如何将数组json数据转换为jquery中的特定json？

Question

我在 jquery 中得到一个 JSON 数组，现在我想将此数组 json 数据转换为特定的 JSON 数据。我使用 arr.push 创建这个 json。现在我想改变这个格式：

[
    {
        "question": {
            "QuestionType": "QShortText",
            "Question": "What's your name?",
            "PlaceHolderText": "Placeholder",
            "IsNumericOnly": true,
            "CharacterLimit": 0,
            "IsRequired": true
        }
    },
    {
        "Paragraph": {
            "QuestionType": "QPargraphText",
            "Question": "789",
            "PlaceHolderText": "ytut",
            "CharacterLimit": 0,
            "IsRequired": true
        }
    }
]

转成这种格式：

{
    "question": {
        "QuestionType": "QShortText",
        "Question": "What's your name?",
        "PlaceHolderText": "Placeholder",
        "IsNumericOnly": true,
        "CharacterLimit": 0,
        "IsRequired": true
    },      
    "Paragraph": {
        "QuestionType": "QPargraphText",
        "Question": "789",
        "PlaceHolderText": "ytut",
        "CharacterLimit": 0,
        "IsRequired": true
    },
}

我试过这样做：

arrayJsonModel.push({ question: arrayJson[0] })

使用reduce 并传播：

const data = [{"question":{"QuestionType":"QShortText","Question":"What's your name?","PlaceHolderText":"Placeholder","IsNumericOnly":true,"CharacterLimit":0,"IsRequired":true}},{"Paragraph":{"QuestionType":"QPargraphText","Question":"789","PlaceHolderText":"ytut","CharacterLimit":0,"IsRequired":true}}];
const output = data.reduce((acc, curr) => ({ ...acc, ...curr }), {});
console.log(output);
