Problem Statement
What is the main difference between a query and a mutation in RTK Query?
Explanation
Queries are endpoints used for reading data and have automatic caching and refetching behavior, typically corresponding to GET requests, while mutations are for creating, updating, or deleting data and trigger cache invalidation without automatic refetching, typically using POST, PUT, PATCH, or DELETE. Queries can be triggered automatically when components mount or dependencies change, whereas mutations must be manually triggered by user actions. RTK Query treats these differently to optimize data management and performance.
