const qATest = [
  ['What color is the moon?', 'white'],
  ['What year was Javascript born?', '1995'],
  ['What is the name of the crypto sock business?', 'sockhodler'],
  ['Will I ever become a true programmer?', 'yes']
];

let answerCorrect = 0;

for ( let i = 0; i < qATest.length; i++ ){
  const questions = prompt(qATest[i][0]);
  if (questions.toLowerCase() === qATest[i][1]) {
    answerCorrect++;
  }
}

document.querySelector('main').innerHTML = `

<h1>You got ${answerCorrect} question(s) correct</h1>

`;

Please let me know if anyone has any feedback on how to improve my code at this point.

Looks good so far. As shown later in the video, the instructor uses arrays and a function to make the code a bit more compact, but that's only a slight improvement and not necessary at all to meet the stated objectives.

Good job!   :+1:
