JavaScript JavaScript Basics (Retired) Making Decisions with Conditional Statements Combining Multiple Tests Into a Single Condition

Using II with strings

So I am trying to do the multiple outcome conditions challenge with the option of allowing quiz takers to guess again if they get the answer wrong. So if I type in just the letter to answer the question, it runs correctly. It prompts me to guess again. However, if I type in the full name, I am not prompted to guess again. The program runs to the last else statement. Am I using the II operator wrong?

var correct = 0; 
var wrong = 0; 

var answerA = "Peter Parker";
var answerA1 = "A";
var answerB = "Bruce Wayne";
var answerB1 = "B";

var quiz = false; 

var question1 = prompt("What is Spiderman's Real Name A. Peter Parker or B. Bruce Wayne?");
if(question1.toUpperCase() === answerA.toUpperCase() || question1.toUpperCase() === answerA1) {

quiz = true; 

}
  else if (question1.toUpperCase() === answerB || question1.toUpperCase() === answerB1) {
    var again = prompt('Sorry! You\'re wrong. Guess  again!'); 
      if(again.toUpperCase() === answerA.toUpperCase() || again.toUpperCase() === answerA1) {
        quiz = true;  
      }
  }

if(quiz) {
correct += 1; 
alert('You have ' + correct + ' answers correct and ' + wrong + ' answers wrong'  ); 
}
else {
wrong += 1; 
alert('You have ' + correct + ' answers correct and ' + wrong + ' answers wrong' ); 
}

Hey Lorraine,

Try changing the else if to just an else. With the if statement, you are checking to see if the question has been answered correctly. Because you only have two choices in this example, you don't need an else if. The conditionals are right, and with this change, it worked in my console.

else {
    var again = prompt('Sorry! You\'re wrong. Guess  again!'); 
      if(again.toUpperCase() === answerA.toUpperCase() || again.toUpperCase() === answerA1) {
        quiz = true;  
}

Give that a try. :dizzy:

I can not spot the problem, but I can see you're missing 1 thing:

again.toUpperCase() === answerA1)

You're missing the starting ( after answerA1

I hope you get the problem solved very soon :-)

After playing around some bit, I was able to find a solution. I had to add an extra set of parentheses around each condition.

var correct = 0; var wrong = 0;

var answerA = "Peter Parker"; var answerA1 = "A"; var answerB = "Bruce Wayne"; var answerB1 = "B";

var quiz = false;

var question1 = prompt("What is Spiderman's Real Name A. Peter Parker or B. Bruce Wayne?"); if((question1.toUpperCase() === answerA.toUpperCase()) || (question1.toUpperCase() === answerA1.toUpperCase())) {

quiz = true;

} else if ((question1.toUpperCase() === answerB.toUpperCase()) || (question1.toUpperCase() === answerB1.toUpperCase())) { var again = prompt('Sorry! You\'re wrong. Guess again!'); if(again.toUpperCase() === answerA.toUpperCase() || again.toUpperCase() === answerA1) { quiz = true;
} }

if(quiz) { correct += 1; alert('You have ' + correct + ' answers correct and ' + wrong + ' answers wrong' ); } else { wrong += 1; alert('You have ' + correct + ' answers correct and ' + wrong + ' answers wrong' ); }

var question2 = prompt('What colors are Spiderman\'s costume? A. Blue and Red or B. Green and Purple?'); var answerC = "Blue and Red"; var answerC1 = "A"; var answerD = "Green and Purple"; var answerD1 = "B";

if((question2.toUpperCase() === answerC.toUpperCase()) || (question2.toUpperCase === answerC1.toUpperCase())) { quiz = true;
} else if ((question2.toUpperCase() === answerD.toUpperCase()) || (question2.toUpperCase() === answerD1.toUpperCase())) { var again = prompt('Sorry! You\'re wrong. Guess again!'); if((again.toUpperCase() === answerA.toUpperCase()) || (again.toUpperCase = answerA1.toUpperCase())) {

   quiz = true;  
  }

}

if(quiz) { correct += 1; alert('You have ' + correct + ' answers correct and ' + wrong + ' answers wrong' ); } else { wrong += 1; alert('You have ' + correct + ' answers correct and ' + wrong + ' answers wrong' ); }
