A

GraphQL is a query language for APIs and a runtime for executing those queries with your existing data. It provides an efficient and powerful alternative to REST.

99
Q

What is the difference between REST and GraphQL?

A

The main difference between REST and GraphQL is how data is requested and delivered. In REST, you would have to make multiple requests to different endpoints to fetch related pieces of data.
