javascript - Codecademy javascript 第 7/9 课错误

Question

我已经在 7/9 被困了 2 个晚上了。这是一个石头剪刀布的游戏。我不知道出了什么问题。我尝试了在线 lint，它还说我的第 22 行是一个错误(需要一个标识符，但看到的是“else”)。按照说明，我在比较函数内的现有代码下编写了另一个 else if 。

我的代码:

var userChoice = prompt("Do you choose rock, paper or scissors?");
var computerChoice = Math.random();
if (computerChoice < 0.34) {
computerChoice ="rock"
} else if(computerChoice <= 0.67) {
computerChoice ="paper";
} else {
    computerChoice ="scissors";
} console.log("Computer: " + computerChoice);
var compare=function(choice1, choice2){
if(choice1 === choice2) {
    return("The result is a tie!");
}
else if(choice1 ==="rock"){
    if(choice2 ==="scissors")
    return("rock wins");
}
else{
    return"paper wins";
}
    else if(choice1 ==="paper");{
    if(choice2 ==="rock")
    return("paper wins");
}
else{
    return"scissors wins";
}
}

Answer 1

var userChoice = prompt("Do you choose rock, paper or scissors?");
var computerChoice = Math.random();
if (computerChoice < 0.34) {
computerChoice ="rock"
} else if(computerChoice <= 0.67) {
computerChoice ="paper";
} else {
    computerChoice ="scissors";
} console.log("Computer: " + computerChoice);
var compare=function(choice1, choice2){
if(choice1 === choice2) {
    return("The result is a tie!");
}
else if(choice1 ==="rock"){
    if(choice2 ==="scissors")
    return("rock wins");
}
else{
    return"paper wins";
}
    else if(choice1 ==="paper");{ -- on this there is semicolon after elseif block.. and how come else if is there after else block.. 
    if(choice2 ==="rock")
    return("paper wins");
}
else{
    return"scissors wins";
}
}
