Have you had experience working with GraphQL and have you used it in projects?

GraphQL is a query language for APIs and a runtime environment that allows clients to request exactly the data they need and nothing more. Unlike REST, where the server defines the response structure, in GraphQL the client constructs the query with the required fields.

Experience with GraphQL typically includes:

• Defining the schema (types, queries, mutations).
• Implementing resolvers on the server (e.g., using Node.js with libraries like graphql or apollo-server).
• Creating queries and mutations on the client.

An example of a simple GraphQL query:

query {
  user(id: "1") {
    id
    name
    email
  }
}

In GraphQL projects, it helps reduce the number of requests to the server and increases flexibility in data retrieval. If you have experience, you can mention using Apollo Client or Relay for frontend integration.
