I learn Clojure. Did that. Love it. Wrote moderately significant
application. Very comfortable with Clojure.
Clojurescript: Leiningen or boot, but either way it's more complicated. OK.
Want to get started.

This version isn't supposed to have implemented spec/double-in yet, right?
I get "Use of undeclared Var cljs.spec/double-in".
Sorry to ask--I don't know my way around JIRA well, and searching for
"double-in" brings up a lot of irrelevant tickets.
Thanks much.

clojure.spec/double-in defines a spec that tests whether a double is greater
than or equal to a minimum value and less than or equal to a maximum value.
This is useful for many purposes, but sometimes you need to test whether a
double is greater than a minimum or less than a maximum. There

This behavior seems to have to do with Reagent; it goes away when I get rid of
Reagent and use an HTML file instead.

This looks very, very nice. The instant feedback is especially helpful.
(You are probably already working on is capturing errors to make them less
daunting.)
Klipse reminded me of Carin Meier's beautiful and poignant Hello World for
the Next Generation.
Though I have quite a bit of experience with Clojure, but I'm *very* new to
Clojurescript and to all of the tools mentioned below except (sort of) d3.js.
I have a little experimental app using reagent with figwheel. I'm using NVD3,
a d3.js chart library, to create an SVG chart. I finally got
I'm just starting out with Clojurescript (though I know Clojure pretty well),
so my comments might be misguided. However, to me it seems like it would be
difficult to get very far with Clojurescript without knowing a little bit about
Javascript. I have had to use what I know about Javascript
There's also cljs.pprint/cl-format, which is portable between Clojurescript and
Clojure (there as clojure.pprint/cl-format).

Thanks very much. I didn't understand that the :refer

No one's commented on this, but I keep wanting to comment. I know that it's
the same content as the old site, and the same format as clojure.org, but I
still think it's great. (Sorry!)

A good rule of thumb: One should worry that giving end-users access to a
full-fledged eval function can be dangerous, because users can then do anything
that the language can do, and cause damage to their own system or to others'.
There are numerous Clojurescript repls embedded in public web

I'm trying to define two versions of a macro, one for Clojure and one for
Clojurescript, using reader conditionals.
I end up seeing the Clojure version in Clojurescript. I assume this happens
because the macro definition is processed by Clojure, before Clojurescript
runs, so it's the #?(:clj

Ah, I was wondering about that. More complexity. Or maybe less, if one could
