6,357 PointsWhen i prompt the questions, all of the questions i my array and answers pop up in every PROMPT box?
this is my code, its just like the video
const questions = [ ['What is the capitol of California','sacramento'], ['How many states are the in the USA?', '50'], ['How many fingers in the regular hand?', '10'] ];
let correctAnswers = 0;
for (let i = 0; i < questions.length; i++) { let question = questions[i][0]; let answer = questions[i][1]; let response = prompt(questions);
if (response === answer) {
correctAnswers++
}

9,540 PointsIt shows all the questions, because you put the whole array in the prompt method instead of a single question.
This:
let response = prompt(questions);
Should be changed to this:
let response = prompt(question);
The code will therefore look like this:
const questions = [ ['What is the capitol of California','sacramento'], ['How many states are the in the USA?', '50'], ['How many fingers in the regular hand?', '10'] ];
let correctAnswers = 0;
for (let i = 0; i < questions.length; i++) {
let question = questions[i][0];
let answer = questions[i][1];
let response = prompt(question);
if (response === answer) {
correctAnswers++
console.log(correctAnswers);
}
}
I would prefer using a foreach method on the array instead of a for loop:
// Go through each question in the questions array
questions.forEach(question => {
// Get the correct answer from the array
let answer = question[1];
// Show the prompt with the question and get the response from the user
let response = prompt(question[0]);
// Check if the user response is the same as the answer from the array
if (response === answer) {
// Add 1 to the "correctAnswers" variable if the answer is correct
correctAnswers++
}
});
