AWS AppSync now supports JavaScript for all resolvers in GraphQL APIs

AWS AppSync is a managed service that makes it easier to build scalable APIs that connect applications to data. With AppSync, API developers can write resolvers to define the business logic that connects their AppSync GraphQL and Pub/Sub APIs to data. Now, developers can use JavaScript to write their unit resolvers, pipeline resolvers, and AppSync functions that are executed on the AppSync JavaScript (APPSYNC_JS) runtime.
