The official website of graphQL says: GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data Send a GraphQL query to your API and get exactly what you need, nothing more and nothing less. GraphQL queries always return predictable results. Apps using GraphQL are fast and stable because they control the data they get, not the server. I borrowed from the official website, the pictorial representation of a graphQL query and response.
We live in a world that mostly relies on increasingly on digital data day-by-day the data is going on increasing Every picture you take, every snapchat you send, every Instagram you post, every message that you text in this way it is going on increasing and creates more and more data.
