Does rejecting Promise.all cancel the remaining operations?
Short interview answer
No. Their results are ignored by that aggregate, but the underlying fetches or other work continue unless they support cancellation and you invoke it. AbortController is commonly used to coordinate fetch cancellation.
Key takeaway
Explain the underlying mental model clearly, then support it with a concrete example and its trade-offs.
