The intention of this road map is to share with you our own learning experience (one of many paths you can take to grok the language) and to draw you to the highest quality information (which we won't be ever able to write in a better way) keeping you on the implementation agnostic spirit of the language, providing abstract examples as well as practical exercises in different languages so you can understand the correlations and differences without losing focus on the main topic: GraphQL. We'll walk through this starting from the language and the API definition on the backend, gradually increasing the complexity as the walk develop; it might contain new examples on the future, or more "days" including client-side, testing or architecture specific topic, or we might create another walk for them, we don't really know.
