What is GraphQL?
An alternative to REST APIs that lets you request exactly the data you need in a single call
Why It Matters
GraphQL can make your app faster by reducing unnecessary data transfer and simplifying complex data requests
Real-World Example
Instead of making three separate API calls for user details, posts, and comments, GraphQL lets you get all three in one request
