Could the useState be used without the setter?

I have a question... could the useState be used without using the setter? because a teammate use it in that way to get an item from sessionStorageconst [initialScrollPosition] = useState(() => Number.parseFloat(sessionStorage.getItem('offset') || 0)); and argues that this is so that the component is not unnecessarily rerendered and to read the sessionStorage only once! 🤔 but I think we can use useMemo for those cases but the useState is still used in this form in several components.useState lazy initialization and function updates
