Why we should use REST? [closed]

Answer 1

Using REST correctly can help your system components remain properly decoupled and can be evolved more easily in the future than if you had tied them directly together in a typical RPC-like fashion. It's an architectural choice that you must make based on your application's needs. Others have noted some of the technical benefits, and they should be taken into account too.

Answer 2

REST allows easy evolution of an API design. And that's the key with REST - you're creating an API. Some of the comments have touched on aspects of this thought, but have not actually brought the core issue to life. When you are dealing with REST, you are creating an API that would be used by clients (or yourself). The HTTP actions on the resources give a clear indication to the clients of the API design and functionality. Therefore, when we use the correct HTTP verbs properly, we are declaring an API that is standardised and understandable from a client perspective.
