是否可以在JavaScript中创建异或双向链表？

class Node {
  constructor(value) {
    this.value = value;
    this.xor = null;
  }
}

class XORLinkedList {
  constructor() {
    this.head = null;
    this.tail = null;
  }

  add(value) {
    const newNode = new Node(value);

    if (!this.head) {
      this.head = newNode;
      this.tail = newNode;
    } else {
      newNode.xor = this.tail;
      this.tail.xor = newNode;
      this.tail = newNode;
    }
  }

  traverseForward() {
    let current = this.head;
    let prev = null;

    while (current) {
      console.log(current.value);

      const next = current.xor ^ prev;
      prev = current;
      current = next;
    }
  }

  traverseBackward() {
    let current = this.tail;
    let prev = null;

    while (current) {
      console.log(current.value);

      const next = current.xor ^ prev;
      prev = current;
      current = next;
    }
  }
}

// 创建一个异或双向链表
const list = new XORLinkedList();

// 添加节点
list.add(1);
list.add(2);
list.add(3);

// 正向遍历
list.traverseForward();

// 反向遍历
list.traverseBackward();
