I don't think doing this inside a for loop works correctly? Trying to figure out another method of doing this?

Any suggestions for a method to code this?

Please post your code, or even better, make a snapshot of your workspace and post the link to it here.

here is my code:

var questions = prompt([ ['What my favorite color?', 'green'], ['What is my favorite food', 'pizza'] ]);

var score = 0; var question; var answers; var response; var html;

function display(message){ document.write(message) };

for (i = 0; i < questions.length; i++) { question = questions[i][0]; answers = questions[i][1]; response = prompt(questions); if (response === answers){ score++ } }

html = 'you got' + score + 'questions right'; display(html);

The method is fine but you have a couple of syntax errors.
First, the assignment of the array should not be inside a "prompt" function call:

var questions = [["What my favorite color?", "green"], ["What is my favorite food", "pizza"]];

Then, inside the loop, the real "prompt" call should use "question" (singular) instead of the entire array:

  response = prompt(question);  // not "questions" (plural)

You're absolutely right Steven. I didn't even notice. Thank you.
