[
            {
                name: "ll",
                y: 4
            },
            {
                name: "bb",
                y: 3
            },
            {
                name: "cc",
                y: 1
            }
        ]

怎么样将这样的json格式转成二维数组?

[
    [
        "ll",
        4
    ],
    [
        "bb",
        3
    ]
]

lodash鲁大师没用过吧？

res = []
for (var i in list) {
   var item = [];
    for (var j in list[i]) item.push(list[i][j]);
    res.push(item)
}

伸手党你够了！

function toArr(arr) {
    for (var i=0; i<arr.length; i++) {
        var tmpArr = []
        for (var attr in arr[i]) {
            tmpArr.push(arr[i][attr])
        }
        arr[i] = tmpArr
    }
    return arr
}

    for (var i = 0,item; item = arr[i++];) {
        var temp = [];
        for (var j in item) {
            if (item.hasOwnProperty(j)) temp.push(item[j]);
        }
        arr[i - 1] = temp;
    }
    console.log(arr);
