我正在网站www.codecademy.com上为课程编写此代码。这应该是游戏的一小部分。很抱歉，有这么多错误，如果错误来自，我无法再缩小范围。

语法错误是因为您在发布的代码的第18行缺少一个结束括号。这：

应该是：else {

} else {

if(meetAnt = yes) {

if(meetAnt == "yes") {

if(dayFight < 40) {

dayFight = parseInt(dayFight, 10);

else if(40<=dayFight=>60) {

else if(40 <= dayFight && dayFight <= 60) {

if(postion = wings || mushroom) {

if(postion == "wings" || postion == "mushroom") {

return true;
console.log("congratulations you have killed the aint eater!")

console.log("congratulations you have killed the aint eater!")
return true;
