Exercise: GraphQL Mutations

Now, let’s practice some of our newly acquired skills and try to implement support for voting for products in our application. Since we already have some experience with implementing GraphQL resolvers, the new mutation is already implemented for us. Let’s work on implementing the frontend of the application in this exercise.
