async vs parallel
Asynchronous work can yield while waiting; parallel work executes simultaneously.
Use this when I/O waits and CPU work need different execution strategies.

“I made the image processing async but the app still freezes. And when I process 1000 files at once with Promise.all, everything falls over. What's the right way?”
with the term · How do you ask a model for async vs parallel?
Separate the I/O-bound and CPU-bound work here. Use bounded concurrency and verify responsiveness and throughput under representative load.
What is async vs parallel?
Async code overlaps waiting, such as on network or disk. Parallel code runs computation on several cores at once. CPU-heavy work needs workers or threads, not just async.
Why does async vs parallel matter when vibe coding?
Adding async syntax cannot make blocking computation stop occupying its executor.
How do you do async vs parallel?
Classify the workload and choose bounded overlap or worker execution as appropriate.
What goes wrong with async vs parallel?
Starting an unbounded task for every item and exhausting a downstream resource.
