Rest API - Rate Limiting and Throttling

Which of the following is the correct syntax to access the X-RateLimit-Reset header in a JavaScript fetch response object named response?

Aresponse.get('X-RateLimit-Reset')

Bresponse.getHeader('X-RateLimit-Reset')

Cresponse.headers['X-RateLimit-Reset']

Dresponse.headers.get('X-RateLimit-Reset')

Step-by-Step Solution

Solution:

Step 1: Recall fetch API header access method
In fetch, headers are accessed with headers.get('header-name').
Step 2: Check other options for correctness
response.getHeader and response.get do not exist; headers['name'] is not valid for Headers object.
Final Answer:
response.headers.get('X-RateLimit-Reset') -> Option D
Quick Check:
fetch headers use headers.get('name') [OK]

Quick Trick: Use headers.get('Header-Name') to read fetch response headers [OK]
