This commit upgrades Shadow CLJS from 2.11.16 (released on Feb/21) to latest
2.25.0 (Jul/23), so ~1.5 years worth of upgrades. By upgrading shadow we
can finally use the latest major Clojure version 1.11.x.
Why upgrade shadow?
- Shadow CLJS controls the ClojureScript version we can use. In order to use the
latest major Clojure version we must upgrade Shadow CLJS.
- Shadow CLJS releases new versions very frequently, and if you take a look at
its changelog https://github.com/thheller/shadow-cljs/blob/master/CHANGELOG.md, you'll see
it had tons and tons of bug fixes over the years. I hope some of them help
improve the DX for certain contributors who recently reported issues with
it.
- Clojure 1.11 brings new features, bug fixes and even performance improvements
(although I think the performance mostly impacts Clojure on the JVM). See the
changelog https://github.com/clojure/clojure/blob/master/changes.md#changes-to-clojure-in-version-1110
Things that can be beneficial to us, or are interesting nonetheless:
- New :as-alias to be used in require, which is like :as but does not require
the namespace to load. This means namespaced keywords using :as-alias can't
cause circular dependency errors. This feature would very useful if we used
namespaced keywords, but we don't, so...

- New macros run-test and run-test-var to run single test with fixtures and
report.
- New iteration function, useful for processing paginated data.

- New update-keys function: applies a function to every key in a map.
- New update-vals function: applies a function to every value in a map.
Examples for update-vals and update-keys. They should perform better than the
common reduce-kv approach since they use a transient data structure.
(let [m {:a 1 :b 2}]
(update-vals m inc)) ; => {:a 2, :b 3}
(let [m {:a 1 :b 2}]
(update-keys m name)) ; => {"a" 1, "b" 2}
Why change namespaces within __tests__ directories?
Any namespace with the word --tests-- throws an error, like the one below. I
didn't bother investigating why, so I changed the guidelines to reflect the new
convention. It's probably related to the double dashes in the name.
Namespace quo2.components.dividers.--tests--.divider-label-component-spec has a
segment starting with an invalid JavaScript identifier at line 1
