In my [questions] array, one of the answers is a number.

At first I tried using a strict equality in my if statement "===" but the second question wouldn't be logged as correct.

I had to change to the if condition to "==" for it to work.

Is there a reason for this that I might have missed?

```// 1. Create a multidimensional array to hold quiz questions and answers

let questions = [
["This should be 'y'? y/n","y"],
["This should be 34? y/n",34],
["This should be 'y'? y/n","y"]
];

// 2. Store the number of questions answered correctly

let score = 0;

/*
3. Use a loop to cycle through each question
- Present each question to the user
- Compare the user's response to answer in the array
- If the response matches the answer, the number of correctly
*/

for (let i = 0; i < questions.length; i++) {

if ( answer == questions[i]) {
score += 1;
console.log(score);
}
}

// 4. Display the number of correct answers to the user

let html = `
<h1>You scored <strong>\${score}</strong>/3 points</h1>
`;

document.querySelector('main').innerHTML = html;
``` The `strict equality` check can and will often lead to problems like you are experiencing. With this operator, the check will be for BOTH `value` and `type`.
When you are using `prompt` in JavaScript, the input will always be a string. So, when you put 34 as the answer to the question, the compiler reads "34"... which does not === 34, as one is a string and one a number.
Unless the coding requires you to check for both value and type, `strict equals` is not a very popular operator.
Hope that helps. :)
