将json数组中多个字段组合为新数组

Question

怎么将

[ 
    {   
        "articleId": 55,
        "title": "第一篇文章",
        "uid": 43,
        "username": "admin",
        "userAvatar": "admin.jpg"
     },
     {  
        "articleId": 56,
        "title": "第二篇文章",
        "uid": 44,
        "username": "test",
        "userAvatar": "test.jpg"
     },
]

变为

[ 
    {   
        "articleId": 55,
        "title": "第一篇文章",
        "userinfo":{
            "uid": 43,
            "username": "admin",
            "userAvatar": "admin.jpg"
        }
     },
     {  
        "articleId": 56,
        "title": "第二篇文章",
        "userinfo":{
            "uid": 44,
            "username": "test",
            "userAvatar": "test.jpg"
        }
     },
]
