🚀 REST vs GraphQL

Both are used to build APIs. 
But they handle data fetching differently.


1️⃣ REST (Representational State Transfer) 🌐

Uses multiple endpoints to access resources.

➤ How: Each resource has a fixed URL 
➤ Example: 
   GET /users 
   GET /users/1 
➤ Wins: Simple, widely adopted 
➤ Risk: Over-fetching or under-fetching data 

Problem:
Client may receive more data than needed.


2️⃣ GraphQL ⚡

Uses a single endpoint for all requests.

➤ How: Client specifies exactly what data it needs 
➤ Example:

{
  user(id: 1) {
    name
    email
  }
}

➤ Wins: No over-fetching, flexible queries 
➤ Risk: More complex setup 


💡 Key Difference

REST → Multiple endpoints, fixed responses 
GraphQL → Single endpoint, flexible responses 

REST = Server defines structure 
GraphQL = Client defines structure 

Choose based on project complexity.
