SyntaxError（CODEACADEMY）

Question

我遇到以下問題。任何幫助，將不勝感激。我的電腦指出以下內容：

Oops, try again. There was a problem with your syntax. SyntaxError: missing) after condition.

可以找到？或者還有其他一些問題？任何信息/想法/想法都會受到讚賞。

這裏是我的代碼：

// Check if the user is ready to play! 
confirm ("I am ready to play!"); 
var age = prompt ("What's your age"); 
if (age is less than 13); 
{ 
    console.log ("You can't play this game!"); 
} 
else 
{ 
    console.log ("This game was created for you. Play on!"); 
} 

Answer 1

您使用不正確的語法。使用​​而不是if (age is less than 13);。請注意，關閉後沒有;)
