## 递归实现
  const getCurrentPath = (node, keyword) => {
      const result = [];
      const exec = (node, path) => {
        const currentPath = path.concat(node.label);
        if (node.label.search(keyword) !== -1) {
          result.push(currentPath);
        }
        if (Reflect.has(node, 'children') && node.children.length > 0) {
          node.children.forEach(child => {
            exec(child, currentPath);
          });
        }
      }
      exec(node, []);
      return result
    }
    testData.forEach(item => {
      console.log(getCurrentPath(item, 'Level three 2-1-1'));
    })
