Why does my code stop when i enter the right question?

When i enter 'Carlos' for the first question, it just stops after that. carlos is the right answer. This is my code :

const score = 0; var questions = [ ['What is my name?', 'carlos'], ['What is the sate where the golden gate bridge is located?', 'california'] ] for (let i = 0; i < questions.length; i++) { let question = questions[i][0]; let answer = questions[i][1]; let userAnswer = prompt(question);

if (userAnswer === answer) {
    score++;
}

} var msg = alert(You got ${score} correct);

The variable "score" is created as a constant with value 0. But when the answer is correct, the code attempts to increment the value. Changing the value of a constant is not allowed and the error causes the program to stop.

To allow it to be changed, create "score" with 'let" or "var" instead of "const".
