Notes

¹ Lagged / "Lazy" Queries - React Query provides a way to continue to see an existing query's data while the next query loads (similar to the same UX that suspense will soon provide natively). This is extremely important when writing pagination UIs or infinite loading UIs where you do not want to show a hard loading state whenever a new query is requested. Other libraries do not have this capability and render a hard loading state for the new query (unless it has been prefetched), while the new query loads.

² Partial query matching - Because React Query uses deterministic query key serialization, this allows you to manipulate variable groups of queries without having to know each individual query-key that you want to match, eg. you can refetch every query that starts with todos in its key, regardless of variables, or you can target specific queries with (or without) variables or nested properties, and even use a filter function to only match queries that pass your specific conditions.

³ Automatic Refetch after Mutation - For truly automatic refetching to happen after a mutation occurs, a schema is necessary (like the one graphQL provides) along with heuristics that help the library know how to identify individual entities and entities types in that schema.
