What does it solve?

• fetching unnecessary data (overtfetching data)

• graph: a data structure that contains nodes and the relations between them (edges)
• edges are functions that resolve relationships between nodes

Query Variables

• inject variables into a mutation

    user(id: "23") {
        friends() {
            company {
                name
            }
        }
