Arrays screeps.com:简单脚本不工作，二维数组出现问题

我从控制台收到以下错误：“TypeError:无法读取未定义的属性“0”，它与数组有关，但我找不到错误

module.exports =
{
    create_creeps: function() 
    {

        var aHarvester  = [[TOUGH,TOUGH, MOVE, CARRY, WORK, MOVE]["harvester"]];

        Spawn.prototype.createMyCreep = function(aCreep,sRole) {
            if (!Game.spawns.Spawn1.spawning){

                var nameCount = 0;
                var name = null;
                while(name == null)
                {
                    nameCount++;
                    var tryName = sRole + nameCount;
                    if(Game.creeps[tryName] == undefined)
                        name = tryName;
                }
                var dbg= this.canCreateCreep(aCreep, name);
                if(dbg  == OK) {
                    console.log("Creating creep " + sRole);
                    return this.createCreep(aCreep , name,{ role:sRole });
                } else {
                    console.log("error "+dbg+" "+sRole);
                }
            } 
        };

        Game.spawns.Spawn1.createMyCreep(aHarvester[0],aHarvester[1][0]);

    };
}

请用逗号分隔数组

所以

应该是

[[TOUGH,TOUGH, MOVE, CARRY, WORK, MOVE],["harvester"]]

[[TOUGH,TOUGH, MOVE, CARRY, WORK, MOVE],["harvester"]]
