听起来您只想从 API 响应中重构数据。这是一种解决方案：

const data = {
    ...
    "Response": {
        "Data": {
            "DataHolder": [
                {
                    "abc": "abc description"
                },
                {
                    "def": "def description"
                },
                {
                    "ghi": "ghi description"
                }
            ]
        }
    }
};
const descriptions = data.Response.Data.DataHolder.map(item => Object.values(item)[0]);

// ["abc description", "def description", "ghi description"]
