Why the questions are not popping up?

This is my code and the questions are not even popping up. Why?

const questions = [["What is the capital city of France?", "Paris"], ["What is the capital of Spain?", "Madrid"], ["What is the capital of Slovakia?", "Bratislava"]
];

let correctAnswers = 0;

for (let i = 0; i < questions.lenght; i++) { let question = questions[i][0]; let answer = questions[i][1]; let response = prompt(questions);

if (response === answer) { correctAnswers += 1; } }

let html = <h1>You guessed ${correctAnswers} question(s).</h1>;

document.querySelector("main").innerHTML = html;

  1. You have a typo: for (let i = 0; i < questions.lenght; i++)
  2. This should just be question, not questions: prompt(questions);
  3. This, <h1>You guessed ${correctAnswers} question(s).</h1>, should be surrounded by backticks.
