You need to fetch data for 100 items asynchronously but want to limit concurrency to 10 requests at a time to avoid server overload. Which approach correctly implements this in JavaScript?

Rest API - Batch and Bulk Operations

AProcess the URLs in chunks of 10, awaiting Promise.all for each chunk before proceeding

BSend all 100 fetch requests at once using Promise.all without batching

CUse a forEach loop with async fetch calls without awaiting them

DFetch each URL sequentially using a for loop with await inside

Step-by-Step Solution

Solution:

Step 1: Understand concurrency control
To limit concurrent requests, divide the total URLs into smaller batches.
Step 2: Implement batching
Process each batch of 10 URLs with Promise.all and await completion before starting the next batch.
Final Answer:
Process the URLs in chunks of 10, awaiting Promise.all for each chunk before proceeding -> Option A
Quick Check:
Batching controls concurrency, prevents overload [OK]

Quick Trick: Batch requests and await each batch to limit concurrency [OK]

Common Mistakes:

MISTAKES

Sending all requests simultaneously causing overload
Not awaiting fetch calls leading to unhandled promises
Fetching sequentially causing slow performance
