Each asset you create comes with its own cache. When you request something from it, the arguments that you pass will act as cache-keys. If you request later on using the same keys, it won't have to re-fetch but serves the result that it already knows. You can also use the useAsset hook, which is modelled after react-promise-suspense. This makes it possible to define assets on the spot instead of having to define them externally. They use a global cache, anything you request at any time is written into it.
