Quiz App with Jquery - Check Answer

Hello everyone,
I am working on a Quiz App and I am stuck on checking my answer. My button to check my answer resets my quiz. I would like to know if I am on the correct track. I don’t want the issue solved however I would like to know if I am headed in the right direction and if my logic makes sense.

Warm Regards!

Mind showing your HTML too?

Also, you call callAllFunctions when the page is loaded. This function calls 4 function, but you only need to call one. Which one do you think it should be? Once you figure that out, then you could get rid of the callAllFunctions function and use the single function as the callback for when the page is loaded.

$('.jsList').on('click').append(quizQuestions);

If you are trying to append the quizQuestions HTML to an element with class=“jsList”, when the “Let’s Go!” button is clicked, this is not the way to do it. The on(‘click’) is not doing anything for you here.
