GraphQL
Definition
GraphQL is a query language for your API. Instead of multiple endpoints, there is only one (`/graphql`). The client explicitly requests exactly the shape of the data it needs, solving the over-fetching and under-fetching problems of REST.
Explain Like I'm New
Instead of ordering off a fixed menu, GraphQL is a buffet where you tell the chef exactly what you want on your plate: 'I want a user, but ONLY their first name and their top 3 friends'.
