Key Differences Between REST and GraphQL

1. Data Fetching:

   • With REST, you need to use different URLs for different types of data.
   • GraphQL uses just one URL to get all the data.

2. Data Structure:

   • REST gives you a fixed type of data every time you ask for it.
   • GraphQL lets you decide what specific data you want to see.

3. Over-fetching and Under-fetching:

   • In REST, about 75% of the time, you might get too much data or not enough.
   • GraphQL helps you get only the data you need. This means fewer requests over the internet.

4. Versioning:

   • REST usually needs different versions when things change.
   • GraphQL can show you what it has, so you don’t often need different versions.
