Introduction to GROQ Query Language

GROQ (Graph-Relational Object Queries) is a query language for JSON. This course will help you build your first query and walk you through filters, projections, functions, and the other features of GROQ to help you request exactly the data that you want.
In this course, John Lindquist will teach you how to create and structure GROQ queries to load exactly the data you want.
The course will kick off by giving you a quick introduction on what GROQ is, and then you will learn how to use the different features the language supports.
At the end of this course you will know how to use GROQ in the context of a Sanity.io dataset.
