Syntax Error: Unexpected token Else

问题:

I am learning Javascript via Codecademy and no have been stumped on this little piece here.

I have supposed to write an if else statement.

It shows me here in the following that there is a Syntac Error with a missing identifier:

var userAnswer = prompt("Are you feeling lucky, punk?");

if (userAnswer === "yes");
{

    console.log("Batman hits you very hard. It's Batman and you're you! Of course Batman wins!");
}

 else {

    console.log("You did not say yes to feeling lucky. Good choice! You are a winner in the game of not getting beaten up by Batman.");
}

What is wrong with that.... There is no error in this example here:

if (age < 18)

{

    console.log("We take no actions or responsibility. Play at your own risk!");
}

else

{

    console.log("Enjoy the game");
}

回答1:

if (userAnswer === "yes");

Remove the semicolon.

回答2:

There's a semi-colon after the first conditional check. Also, you should always put the opening bracket of the conditional branch on the same line as the brackets

回答3:

var age;
age = prompt('How old are you?');
if (age < 18)

{

alert("We take no actions or responsibility. Play at your own risk!");
}

else if(age > 18)

{

alert("Enjoy the game");
}
