javascript - if/else 语句不起作用？

Question

我是编码新手，我不知道自己做错了什么。每次我尝试写一个 if/else 时，它​​都会工作到语句的程度，然后它就不会工作了。

这是我写的:

alert("welcome to chloe's quiz show!")
var name = prompt("contestant, what is your name?")
var help = prompt("is this your first time playing? type 'yes' or 'no'.")
if (help === yes){
alert("the game is easy! all you have to do is type the letter that corresponds with  the correct answer. then press 'ok'.")
confirm("lets get started!")
}
else{
confirm("lets get started then!")
}

Answer 1

改变这一行:

if (help === yes)

为此:

if (help == "yes")

因为 yes 不是变量。
