What is over fetching?

Over-fetching is fetching too much data, meaning there is data in the response you don’t use. Under-fetching is not having enough data with a call to an endpoint, forcing you to call a second endpoint. … GraphQL fixes this problem because it allows you to request which data you want from the server.

What can GraphQL do?

GraphQL is a query language (that’s what the “QL” stands for) for APIs and a runtime for fulfilling those queries with your existing data. Basically, it is used to load data from a server to a client — it’s a way to get data from an API into your application.
