codeacademy if/else javascript

Question

I am follow the course of CodeAcademy for JS, but there's a problem, the script work but I

console.log("You are at a Justin Bieber concert, and you hear this lyric 'Lace my shoes off, start racing.'");
console.log("Suddenly, Bieber stops and says, 'Who wants to race me?'");
var userAnswer = prompt("Do you want to race Bieber on stage?");

if(userAnswer === "yes") {
    console.log("You and Bieber start racing. It's neck and neck! You win by a shoelace!");
}
else {
    console.log("Oh no! Bieber shakes his head and sings 'I set a pace, so I can race without pacing.'");
}

Give me error:

Oops, try again. Did you add an if statement to your code?

Here page: https://www.codecademy.com/courses/javascript-beginner-en-x9DnD/0/5?curriculum_id=506324b3a7dffd00020bf661, it's in Code Your Own Adventure! 5.

well, your code works (the expected output is printed). I'd report this as a bug to codeacademy. — Gerald Schneider

I am guessing it could be a bug in Codeacadamey. Strangely, the code below works and gives me a green icon.

Writing an if, else if and else statement can sort out these questions. It may be because the instructions are not very clear.

// Check if the user is ready to play!
var userAnswer = prompt("Do you want to race Bieber on stage?");

if (userAnswer === 'yes') {
    console.log("You and Bieber start racing. It's neck and neck! You win by a shoelace!");
} else if (userAnswer === 'no') {
    console.log("Oh no! Bieber shakes his head and sings 'I set a pace, so I can race without pacing.'");
} else {
    console.log("Oh no! Bieber shakes his head and sings 'I set a pace, so I can race without pacing.'");
}

Your code works for me in a browser and I can see the result in the browser console window, so I think you should report this as a bug.

However, you are only checking for lower-case yes. Yes or YES will not match the if statement and will run the code in the else block.

You could try:

if(userAnswer.toLowerCase() === "yes") {    
    // Your code here
} else {
    // Your code here
}

That's why I said you should report it to CodeAcademy. I was pointing out that entering Yes wouldn't work as you are only checking for lower-case answers.

As @thalaivar says, it works if you add a check for no. I'd contact CodeAcademy and report this. Let us know what they say.

The content should be as below, it might possible that you have deleted something.

// Check if the user is ready to play!
confirm('I am ready to play');
var age = prompt("What's your age");

if(age < 13){
    console.log("They're allowed to play but you take no responsibility");
} else {
    console.log("Play On");
}
// Check if the user is ready to play!
var introduction  = "You are at a Justin Bieber concert, and you hear this lyric 'Lace my shoes off, start racing.'";

console.log(introduction);
console.log("Suddenly, Bieber stops and says, 'Who wants to race me?'");
var userAnswer = prompt("Do you want to race Bieber on stage?");
if(userAnswer === "yes"){
    console.log("You and Bieber start racing. It's neck and neck! You win by a shoelace!");
} else {
    console.log("Oh no! Bieber shakes his head and sings 'I set a pace, so I can race without pacing.'");
}

Occasionally, Codeacademy incorrectly reports errors in your code based on trivial whitespace differences. Based on the output of your script, you've written your code correctly.

Funnily enough, using a ternary operator instead of an if statement works fine:

// Check if the user is ready to play!

console.log("You are at a Justin Bieber concert, and you hear this lyric 'Lace my shoes off, start racing.'");
console.log("Suddenly, Bieber stops and says, 'Who wants to race me?'");
var userAnswer = prompt("Do you want to race Bieber on stage?");

console.log( userAnswer === "yes" ?
    "You and Bieber start racing. It's neck and neck! You win by a shoelace!" :
    "Oh no! Bieber shakes his head and sings 'I set a pace, so I can race without pacing.'"
);
