如果`if`语句将'prompt`的返回值与数字进行比较，则永远不会执行

我正在写游戏，但我遇到了这个问题:最后的 if 语句(及其所有 else if 语句)从未执行.

I am writing a game and I have this problem: the last if statement (and all its else if statements) are never executed.

这是无效的代码:

const compare = prompt("1.mars, 2.jupiter, 3.moon")

if (compare === 2) {
  confirm("your airplane crashed and you died")
} else if (compare === 1) {
  confirm("you arrived safely")
} else if (compare === 3) {
  confirm("you survived an airplane crash but you need to escape")
}
