hi guys, I got this error while compiling my project with

[org.clojure/clojure "1.9.0-alpha20"]
[org.clojure/clojurescript "1.9.908"]

return new cljs.core.PersistentVector(null, 2, 5, cljs.core.PersistentVector.EMPTY_NODE, [##NaN,##NaN], null);

is this the problem of compiler?

ok, i see a jira ticket for this : https://dev.clojure.org/jira/browse/CLJS-2352

@ghopper I ran into this before. You can use ns name + var name instead of hash

+ that’s more readable for debugging

What produces the test.js file? Is that present in all cljs projects or is it made from one of my files? In my project it contains a:

return new cljs.core.PersistentVector(null, 2, 5, cljs.core.PersistentVector.EMPTY_NODE, [##NaN,##NaN], null);

@rovanion Look near the top of your test.js file and see if it starts with a comment like

// Compiled by ClojureScript 1.9.908

It is compiled by the cljs compiler and provides cljs.test. So that would be a clojurescript core library ns right?

The weird thing is that I don't use cljs.test in any of my source files. Time to check lein deps :tree:

cljs.test comes with cljs - or do you mean you want to know which code is actually using it/

because deps :tree won't show who uses it either

Yeah, why is it being requiered in the first place.

it's part of cljs, so as far as lein is concerned everyone is using it who uses cljs

I'll up my version of cljs then and see if it helps.

Nope, still getting the same error :/

Am on 1.9.908.

@rovanion 1.9.908 is not compatible with the latest clojure 1.9 versions

thheller: Which version should I use?

To run with Clojure 1.9

alpha17 I think

up to alpha20 should work

https://dev.clojure.org/jira/browse/CLJS-2352

alpha20 excluded then

:P

Right, I was up on Clojure beta1.

Bah, I can't seem to shake this issue with ##NaN in the compiled js. Even though the repl says I'm on alpha17 and I've run lein clean and restarted figwheel about 50 times.

IS there anything similar to promise.all in clojure script ?

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise/all

whats wrong with using Promise.all directly?

Promise.all I guess does’t work in IE11

@rnagpal goog.promise/all should work. Your CLJS compilation most likely already has goog.promise pulled in since it's a very common dependency.

@rnagpal Here is a nice post on how to do promise.all with core.async: http://clojurescriptmadeeasy.com/blog/promises-with-core-async.html

In core.async this also does pretty much the same thing as Promise.all: (async/map vector chans)

async/map avoids the typical laziness issues, I take it.

laziness issues? @jstew

With map. Early on in my core.async adventures I made a big seq of threads and thought I could just map the results with clojure.core/map. It was giving me unexpected results until I forced evaluation. But I was doing it all wrong anyway.

yeah, asyn/map takes and returns channels

Does anyone have some recommendation on service workers? Is there any suggested library?
