Are you tired of getting too much data or too little data from your API calls? GraphQL might be just what you need. In this guide, we’ll learn all about GraphQL and how to use it with JavaScript. We’ll start from the basics and work our way up to more advanced topics.

What is GraphQL?

GraphQL is a query language for APIs that was created by Facebook in 2012. Think of it as a smarter way to ask for data from a server. Unlike traditional REST APIs where you get fixed data from fixed endpoints, GraphQL lets you ask for exactly what you want — no more, no less.

Why Choose GraphQL?

1. You get only the data you need
