Summary:

Hi,

I made a small update to the dependency array in useLayoutEffect, changing it from [native] to [native.value] for better precision. Since JavaScript compares objects by reference, this change can lead to a minor performance improvement. Additionally, as useLayoutEffect is render-blocking, I wanted to ensure we optimize its usage as much as possible.

As a micro-optimization and in line with good coding practices, I also changed a let + if variable to const. While the performance gain is minimal, it contributes to cleaner and more consistent code.

Please feel free to review, and I sincerely apologize if I made any mistakes in the process.

Changelog:

[General] [Changed] – Refined useLayoutEffect dependency array from [native] to [native.value] for improved precision and efficiency in re-renders.
[General] [Changed] – Replaced let with const where applicable for better code standards and micro-optimization.
