Rest API - Rate Limiting and Throttling

Consider this pseudocode for a REST API endpoint:

function getUserData() {
  try {
    return fetchUserFromDB();
  } catch (error) {
    return { name: "Guest", id: 0 };
  }
}

What will getUserData() return if the database fetch fails?

AAn error message

BNothing, the function crashes

CNull

DA default user object with name 'Guest' and id 0

Step-by-Step Solution

Solution:

Step 1: Analyze try block behavior
If fetchUserFromDB() works, it returns user data.
Step 2: Analyze catch block fallback
If an error occurs, catch returns default user object with name 'Guest' and id 0.
Final Answer:
A default user object with name 'Guest' and id 0 -> Option D
Quick Check:
Error fallback returns default user object [OK]

Quick Trick: Catch returns default object on failure [OK]
