What Is GraphQL?
GraphQL is a query language for APIs and a runtime for fulfilling those queries against a typed schema. Instead of many fixed REST endpoints, clients send a single request describing exactly the fields they need, and resolvers return that shape.
Why Learn GraphQL with Node.js?
GraphQL eliminates over-fetching and under-fetching, gives clients a strongly typed contract, and pairs perfectly with Node.js through Apollo Server and GraphQL Yoga. Learning it lets you build flexible, efficient APIs that frontend teams love.
