我想在我的文件'question.json'中随机显示HTML中的数据，但不知为何什么都没有发生。我开始学习JavaScript，但还是不知道如何解决。下面是我的代码。
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Answer Something</title>
<script>
$.getJSON('question.json', function(data){
console.log(data)
let questionList = data[Math.floor(Math.random()* data.length)];
let display = document.getElementById('question');
display.innerHTML = questionList;
});
</script>
</head>
<body>
<nav>
<a href="/ask">Quick Ask</a>
<a href="/answers">Quick Answers</a>
</nav>
<h1 id="question"></h1>
<div>
<button>Sai/Không/Trái</button>
<button>Đúng/Có/Phải</button>
</div><br>
<div>
<button>Kết quả vote</button>
<button>Câu hỏi khác</button>
</div>
</body>
</html>
