We need help from an expert like you! Sometimes, programmers are required to be master detectives just to find out what's wrong with their codes. With that being said, you may just be the right person for this! Our system may be have been corrupted by a virus.

Start compiling new data and facts when you take on the Javascript quizzes!

A general thought is that you could always store the correct answer first, and then show the possible answers in a random manner to make your code more DRY. Furthermore: • Since you do not use the id anywhere, you can leave this out: ' id='choice' + (i + 1) + • You could put scoreContainer.textContent = 'Score: ' + score + ' right answers out of ' + quiz.length + ' possible.' ; into it's own function which you could call from askQuestion() so that you do not need to repeat this with scoreContainer.textContent = 'Score: 0 right answers out of ' + quiz.length + ' possible.' ; • Caching the elements is good • JSHint cannot complain about anything • checkAnswer has too much UI state management, it ought to just check the answer. • complited ->completed • Something to think about, finalResults could have read the HTML from a hidden DIV and simply filled in the missing parts. Now you are maintaining HTML in JavaScript which is rarely a good idea.

All in all, I like this code. Just some teeny things: Store the lengths of the arrays in a variable when referencing inside the for loops. This way the functions will only check for the lengths once instead of on each iteration. Function askQuestion() { var choices = quiz[currentQuestion].choices, choicesHtml = ', choicesLength = choices.length; // loop through choices, and create radio buttons for (var i = 0; i.
