使用RxJS完成树浏览的检测

import { from } from 'rxjs';
import { map, filter } from 'rxjs/operators';

// 定义树形结构
const tree = {
  name: 'root',
  children: [
    {
      name: 'node1',
      children: [
        { name: 'leaf1' },
        { name: 'leaf2' }
      ]
    },
    {
      name: 'node2',
      children: [
        { name: 'leaf3' },
        { name: 'leaf4' }
      ]
    }
  ]
};

// 使用RxJS进行树浏览的检测
const traverseTree = (node) => {
  console.log(node.name); // 打印节点名称

  // 递归遍历子节点
  if (node.children) {
    from(node.children).pipe(
      map(child => traverseTree(child))
    ).subscribe();
  }
};

traverseTree(tree);
