我正在为www.codecademy.com网站上的课程编写此代码。它应该是游戏的一小部分。对不起有这么多，我不能再缩小错误来自。
答案 0 :(得分：1)
语法错误是因为您在第18行（已发布代码）中缺少结束括号。这样：
else {
应该是：
} else {
缺少括号表示if之前没有匹配的else。
代码中的其他一些问题，但可能不是全部问题：
在许多陈述结束时，您缺少分号。当语句在行结束时结束时不需要它们，但建议使用它们。
您遇到以下比较问题：
if(meetAnt = yes) {
比较运算符是==（或===），并且您缺少字符串值周围的分隔符，因此它将被解释为变量名称。它应该是：
if(meetAnt == "yes") {
在这些比较中，您会得到意想不到的结果：
if(dayFight < 40) {
变量包含一个字符串，因此值40将转换为字符串"40"以进行比较，并将它们作为字符串而不是数字进行比较。这意味着例如"100" < "40"。您应该将输入字符串解析为数字：
dayFight = parseInt(dayFight, 10);
通过这样的比较，语法是错误的：
else if(40<=dayFight=>60) {
使用两个运算符比较一个值不起作用，并且没有=>运算符。你需要两个条件：
else if(40 <= dayFight && dayFight <= 60) {
在这样的比较中，您使用了||运算符错误（以及错误的比较运算符和缺少的字符串分隔符）：
if(postion = wings || mushroom) {
它在条件之间使用，而不是在一个条件下比较多个值：
if(postion == "wings" || postion == "mushroom") {
当您在return之后放置语句时，该语句将不会执行，因为代码将退出return语句中的函数：
return true;
console.log("congratulations you have killed the aint eater!")
重新排序：
console.log("congratulations you have killed the aint eater!")
return true;
