Javascript Vue.js和Laravel差异返回json和资源

我对两者的区别感到困惑。看起来它们提供了相同的功能。下面是每个控制器的外观示例

返回json控制器

 public function index() {
    $department = Department::orderBy('created_at', 'desc')->get();
    return response()->json($department);
  }

public function index() {
     $department = Department::orderBy('created_at', 'desc')->get();
     return DepartmentResource::collection($department);
  }

返回资源控制器

 public function index() {
    $department = Department::orderBy('created_at', 'desc')->get();
    return response()->json($department);
  }

public function index() {
     $department = Department::orderBy('created_at', 'desc')->get();
     return DepartmentResource::collection($department);
  }

不同之处在于，第一种方法会将model方法触发到array
