Re: More Itertools
#2itertools is a gem and has been since the 2.7 days. Glad to see people waking up to its powerful abstractions.

#3Shout out to JavaScript massively delaying https://github.com/tc39/proposal-async-iterator-helpers in the 23rd hour.
The proposal seemed very close to getting shipped alongside https://github.com/tc39/proposal-iterator-helpers while basically accepting many of the constraints of current async iteration (one at a time consumption). But the folks really accepted that concurrency needs had evolved, decided to hold back & keep iterating & churning for better.
I feel like a lot of the easy visible mood on the web (against the web) is that there's too much, that stuff is just piled in. But I see a lot of caring & deliberation & trying to get shit right & good. Sometimes that too can be maddening, but ultimately with the web there aren't really re-do-es & the deliberation is good.

You can implement quite a lot of Python's itertools in Javascript without too much trouble. For instance, https://observablehq.com/@jrus/itertools
Disclaimer: this code was written several years ago with few downstream users, not all of these are super high performing, and they have not been super extensively tested.

#5Nice! These can make code a ton simpler. Also no python dependencies, which is a requirement for me adopting. Would love to see this brought into the standard lib at some point.

#6it has always annoyed me that flatten isn't already part of itertools
Re: More Itertools
#7This is really helpful. Thank you.
I would like to see some kind of query AST for this stuff in a query engine for semantics that its ops can be fused together for efficiency. For example, like a Clojure transducer.

Amen. For a language that gloats on about "flat is better than nested" you have to jump to too many hoops to get your stuff flattened.

ok itertools has chain.from_iterable but that name is hard to remember
Re: More Itertools
#10I've implemented the "chunked" iterator a million times. Glad to see I can just import this next time.
