javacript가 배열에서 생성되지 않음

나는 한 페이지에 질문과 선택 목록을 생성해야하는 작동하는 자바 스크립트 기능이 있지만 실행되지 않으며 크롬 콘솔에서 실행되는 오류가 없다고 생각합니다.javacript가 배열에서 생성되지 않음

- 함수 두 개가있는 함수 createQestions & createChoices - 나중에 몇 가지 추가 변수가 있습니다.하지만 지금은 질문과 답변 만 표시하고 싶습니다. 일부 함수 호출을 누락 올바른 변수를 호출하지 않는 것처럼

var incorrectCounter = 0;

//empty array to push each selected answer to 
 
var userGuess = []; 
 
var answerKey = ["html", "css", "jquery", "none of the above"];

이 시도? 예를 들어 콧수염. – giubueno

교수님은 우리가 그럴 수 없다고 결코 말하지는 않았지만 그것이 과제의 목적이라고는 생각하지 않습니다. –

이 질문을 하나씩 만들어 낼 수 있습니까? –
