React Cache function

What is React Cache function?

The React cache function allows you to memoize the return value of a function, allowing you to call the same function multiple times while only executing it once.

fetch requests using the GET or HEAD methods are automatically memoized, so you do not need to wrap it in React cache. However, for other fetch methods, or when using data fetching libraries (such as some database, CMS, or GraphQL clients) that don't inherently memoize requests, you can use cache to manually memoize data requests.
