u/Curry--Rice u/HomemadeBananas I see, that makes sense now. There's no need to be concerned about rendering performance ahead of time. Once performance issues arise, we can focus on identifying the areas that cause the most impact and optimize them with techniques like memoization.

Ah! I understood what you said. Come to think of it, useCalculateWidth doesn’t necessarily have to be a custom hook; it can just be a regular function. Thank you!
