with the review

The code patch looks good in terms of syntax. There is no risk of bug. However, if you want to avoid any potential issues in future, it is worth considering to add a comment above the line which has been changed. This will help other developers to understand why the change was made. In addition, you can add unit tests to ensure that the code works as expected.
