Full Stack JavaScript Techdegree Student 9,558 PointsCan my code be better or be writtien easier:
This is my version but what are some changes I can make to make it more easier to read and to make is more simple:
*"guess" is the response
const quizQA = [
['Name?', 'sufi'],
['How many planets are there?', '8'],
['When was javascript created?', '1995']
]
let guess;
let correct = 0;
for (let i = 0; i < quizQA.length; i++) {
guess = prompt(quizQA[i][0]);
let answer = quizQA[i][1];
if (guess.toLowerCase() === answer) {
correct++;
console.log(correct);
}
}
document.querySelector('main').innerHTML = `<h1>You got ${correct}/${quizQA.length} correct!</h1>`;

My only suggestion is that it seems odd to declare "guess" outside the loop but "answer" inside. It might look better with them declared in the same place. Either place will work fine, but since they are only used inside the loop that might be the optimum placement.

let questions = [
['Question 1', 'Answer1'],
['Question 2', 'Answer2'],
['Question 3', 'Answer3'],
]
let correct = 0;
for(let i = 0; i < questions.length; i++){
if( prompt(questions[i][0]) === questions[i][1].) correct++;
}
alert(`Correct Answers ${correct}`);

231,109 PointsLooks like there's a stray period on this line:
if( prompt(questions[i][0]) === questions[i][1].) correct++;
// ^ here
Also, while simpler, this code is not quite functionally identical to the original.
