can figwheel be configured to reload clojure code? according to the documentation this should be possible, but I couldn't figure out how

Hi! Why clojurescript var doesn’t implement alter-var-root?

@kuzmin_m as has been said no vars - so there's nothing to implement

in general you should avoid var oriented programming

some things are possible via macros - but I would consider this a relatively advanced technique

> in general you should avoid var oriented programming Can you explain why I shouldn’t?

vars are mutable

Atoms are mutable too

Hello, what do people use for animation with reagent?

Anybody tried using spring-react with reagent?

React spring I mean: https://www.react-spring.io/docs/hooks/basics

?

in Clojure it works because there are vars and a lot of design around them

in ClojureScript it really requires a an expert understanding of runtime vs. macro time and compiler details

@kuzmin_m i mean in ClojureScript

sorry out of order due to Slack problems

@dnolen so why clojurescript doesn’t implement vars like clojure? Is it performance or closure compiler issues?

ClojureScript doesn't have a runtime, Clojure does

also by eliminating vars you eliminate dynamism which would thwart advanced optimization

Rich Hickey did this design work back in 2011 btw

and it's more or less set in stone for the above reasons

if you have questions about this - Rich Hickey's announce talk in 2011 might cover this

Great. Thanks.

also https://github.com/clojure/clojurescript/tree/master/devnotes

Rich Hickey's original notes are in the repository itself

most of these kinds of questions were answered then

Generic clojure question here. I have an array of maps. Each map has an attribute :id. I want to replace the array element having the :id "foo" with another map. Is there a simple way to do this in clojure/clojurescript?

easy-peasy!
