What the hell is graphQL and why should I care
summary
Explains that GraphQL is a spec/protocol and a strongly typed schema that lets clients declare results, not a database; demonstrates an Express server using Express + express-graphql and shows a demo where the client fetches eight resources in one go. Covers mutations, fragments, nested resolvers, and a naive DataLoader cache (JS Map) plus the proper DataLoader caching pattern for batching and promise-based resolution. Mentions subscriptions, defer/stream ideas, and clients like Apollo, Relay, Lokka.
