What are the key principles of REST?

• Statelessness → Each request is independent; the server doesn’t store client state.
• Client-Server Architecture → Separation of concerns between client UI and server

logic.

• Uniform Interface → Standard HTTP methods and URIs.
• Cacheable → Responses can be cached to improve performance.
• Layered System → APIs can use intermediaries (like load balancers, proxies).
• Resource-based → Everything is treated as a resource (like users, orders,

products).
