GraphQL is a query language for APIs and a runtime for fulfilling those queries with your existing data. GraphQL provides a complete and understandable description of the data in your API, gives clients the power to ask for exactly what they need and nothing more, makes it easier to evolve APIs over time, and enables powerful developer tools. GraphQL Playground ships with basic features such as syntax highlighting, intelligent type ahead of fields, real-time error highlighting and reporting for queries and variables, documentation explorer, search, markdown support, and so much more.
The RS School is working by the principle of 'Pay it forward.' Members of our community share their knowledge and check students' tasks for free. And we hope our students will continue this work as our mentors in the future. Everyone can study at RS School, regardless of age, professional employment, or place of residence. However, you should have sufficient base knowledge before the program begins.
