如何在javascript中创建带条件的树？

// 定义树的节点类
class TreeNode {
  constructor(value) {
    this.value = value;
    this.children = [];
  }
}

// 创建带条件的树
function createConditionalTree(data, condition) {
  // 递归终止条件
  if (!data || data.length === 0) {
    return null;
  }

  const root = new TreeNode(data.value);

  // 遍历数据，根据条件创建子节点
  for (let i = 0; i < data.children.length; i++) {
    const childData = data.children[i];
    if (condition(childData)) {
      const childNode = createConditionalTree(childData, condition);
      root.children.push(childNode);
    }
  }

  return root;
}

// 示例数据
const data = {
  value: 'A',
  children: [
    {
      value: 'B',
      children: [
        {
          value: 'C',
          children: []
        },
        {
          value: 'D',
          children: []
        }
      ]
    },
    {
      value: 'E',
      children: [
        {
          value: 'F',
          children: []
        },
        {
          value: 'G',
          children: []
        }
      ]
    }
  ]
};

// 示例条件：节点值为奇数的节点
const condition = (node) => {
  return node.value % 2 !== 0;
};

// 创建带条件的树
const tree = createConditionalTree(data, condition);

// 打印结果
console.log(tree);
