- If you need to access results of promises running in parallel, use.promise.spread
- To limit concurrency, useWhat are.promise.map
promise.spreadpromise.mapm

09/25/2025, 3:52 PMPromise.map looks relatively similar to Promise.all, but with some extra utilities to help with making things look cleaner. (It is similar to the async.mapLimit function (https://caolan.github.io/async/v3/docs.html#mapLimit) in the Async Library - there are probably other libraries with similar functions too).

09/25/2025, 3:53 PMPromise.spread is similar to Promise.map, but instead of giving you an array of results, it sources that array into a function you provide, so you can have named variable results (which look a little nicer) rather than an array with the results.

09/25/2025, 4:00 PM@burkybang I think so. Now that I think about it... I don't know if Netsuite is using Native Promises or not. I think so... but maybe I'm wrong?

09/25/2025, 4:01 PMI think they are. Promises in server-side SuiteScript seem pretty useless though. They behave synchronously.

09/25/2025, 4:02 PMYeah, you are right. Just checked, and they are native.
Michael Pope
09/25/2025, 4:03 PMAnd yeah, not too useful on the server 😛
