js 数组排序 根据两个字段属性

var task = [
        {name:"aa", taskLevel:"3",createTime:"99"},
        {name:"bb", taskLevel:"2", createTime:"100"},
        {name:"cc", taskLevel:"2",createTime:"99"}
    ];
        
    task.sort(function(a,b){
        if(a.taskLevel === b.taskLevel){
            return a.createTime - b.createTime;
        }
        return a.taskLevel - b.taskLevel;
    });
     
    console.log(task);
试题任务排序，先根据任务紧急度，相同紧急度根据任务创建时间
