我想要显示类别(在给定的例子爱好)基于用户的列表。寻找基于javascript的解决方案

var users = [
  { name: "Alice", hobbies: ["reading", "cooking"] },
  { name: "Bob", hobbies: ["painting", "gardening"] },
  { name: "Charlie", hobbies: ["sports", "music"] }
];

<ul id="user-list"></ul>

var userListElement = document.getElementById("user-list");

users.forEach(function(user) {
  var listItem = document.createElement("li");
  listItem.textContent = user.name;
  userListElement.appendChild(listItem);
});

users.forEach(function(user) {
  var listItem = document.createElement("li");
  listItem.textContent = user.name;
  
  // 根据用户的爱好设置类别
  user.hobbies.forEach(function(hobby) {
    var categoryClass = "category-" + hobby;
    listItem.classList.add(categoryClass);
  });
  
  userListElement.appendChild(listItem);
});
