Rest API - REST API Fundamentals

How does the code on demand constraint affect REST API design, and why is it considered optional?

AIt mandates caching of all responses, optional for performance.

BIt allows servers to send executable code to clients, enhancing flexibility but is optional because not all clients support it.

CIt requires servers to store client state, which is optional.

DIt forces clients to execute all code locally, which is mandatory for REST compliance.

Step-by-Step Solution

Solution:

Step 1: Define code on demand constraint
Servers can send executable code (like JavaScript) to clients to extend functionality.
Step 2: Explain why optional
Not all clients can run code, so this is optional in REST.
Final Answer:
It allows servers to send executable code to clients, enhancing flexibility but is optional because not all clients support it. -> Option B
Quick Check:
Code on demand = optional executable code from server [OK]

Quick Trick: Code on demand is optional server-sent executable code [OK]
