GraphQL Online Test

GraphQL is a query language mainly used for APIs and a runtime for fulfilling those queries with your existing data. GraphQL helps to provide a complete and understandable description of the data in your API.

Clients get what exactly is being asked in the query. GraphQL provides an efficient, robust, and flexible approach to developing web APIs and has been compared and contrasted with REST and other web service architectures. GraphQL makes it easier to evolve APIs over time and enables powerful developer tools. 

GraphQL online test helps recruiters and hiring managers assess candidates’ GraphQL skills. GraphQL skills test is designed by experienced subject matter experts (SMEs) to evaluate and hire GraphQL developers per industry standards.
