What are aliases in GraphQL?

Aliases let you rename a field in the response, and more importantly, they allow you to query the same field multiple times with different arguments in a single request. Without aliases, two calls to the same field would conflict in the response JSON. Example: { alice: user(id: "1") { name } bob: user(id: "2") { name } } returns { "alice": { "name": "Alice" }, "bob": { "name": "Bob" } }. Aliases are widely used when comparing data or fetching variations of the same resource in one round trip.
