用js方法将这个json数组的最大的completeTime对应的nodeName取出 createTime 2023-07-11 165937 updateTime 2023-07-11 170854 createBy 1664144498818551809 updateBy null createDepId C000

你可以使用以下方法来获取json数组中具有最大completeTime的nodeName：

var jsonArray = [
    {
        "createTime": "2023-07-11 16:59:37",
        "updateTime": "2023-07-11 17:08:54",
