如何从具有绝对路径的对象数组构建类似文件系统的JSON

{
  "name": "root",
  "type": "directory",
  "children": []
}

function buildFileSystem(objects) {
  const root = {
    name: "root",
    type: "directory",
    children: []
  };

  objects.forEach(obj => {
    const pathParts = obj.path.split("/");
    let currentDir = root;

    for (let i = 1; i < pathParts.length - 1; i++) {
      const dirName = pathParts[i];
      let dir = currentDir.children.find(child => child.name === dirName);

      if (!dir) {
        dir = {
          name: dirName,
          type: "directory",
          children: []
        };
        currentDir.children.push(dir);
      }

      currentDir = dir;
    }

    const fileName = pathParts[pathParts.length - 1];
    const file = {
      name: fileName,
      type: "file"
    };
    currentDir.children.push(file);
  });

  return root;
}

// 示例用法
const objects = [
  { path: "/root/dir1/file1.txt" },
  { path: "/root/dir1/file2.txt" },
  { path: "/root/dir2/file3.txt" },
  { path: "/root/file4.txt" }
];

const fileSystem = buildFileSystem(objects);
console.log(JSON.stringify(fileSystem, null, 2));
