I always mentally wonder about vs , knowing that 's decision to avoid is very deliberate. But TypeScript is conquering the world; is that an ad populum sign that Types are really a better way to go? Or does ClojureScript offer other things instead? If so, what are they, and to do the benefits of each option find value in different situations?


has a new episode out. Apparently soundcloud doesn't make RSS links obvious for everything, so I grabbed theirs from reversed the URL from Apple Podcasts and plugged it into my readers. feeds.soundcloud.com/users/sou

The language and languages are so stable, with breaking changes being frowned upon in the culture. But breaking in the (frankly, awesome!) tooling has been my difficulty as I maintain a dozen projects of varying ages. It is a real problem.

Wait... do you seriously mean to tell me that I've spent hours debugging the fact that `` is NOT recursive? So ` {"authorizationParams" {"redirect_uri" (-> js/window .-location .-origin)}}` is NOT {"authorizationParams"v {"redirect_uri" (-> js/window .-location .-origin)}}`? I probably read this somewhere, but UGH!

And yes, I know that even fixed this equality wouldn't work because JS always breaks equality... but the point is clear.

I made a site using . The last step was to remove the . But I still use Shadow to start up a local server and explore my static site in-browser. It works nicely as a quick server.

I just had an unexpected error with a VPN script I run every day. I was re-using a shell that was in a directory of a project and got a NPE and "java.lang.Error: Properties init: Could not determine current working directory." It never occurred to me that Babashka might care about my pwd... I suspect I've been missing something valuable.

The original code author was new to the language (this was his first and maybe only project in ) and loved to explicitly return nil and check `(nil?)` all the time. It turns out, it's harder to remove explicit type and `nil?` checks than I thought.

Apparently I need to practice the "refactor so it's idiomatic, without changing the behavior".

The glory of like is supposed to be the smooth experience. I have gone back to the stoneage because github actions are receiving an error that I cannot reproduce locally, so I keep making a change, pushing to see if that effects the github test error, and then trying again. Like I'm back in the stone age.

Stupid errors. Forgot I needed to insert single quotes in my transpiling. But THEN I found out that you can't have - dashes anywhere in variable names in js. My heart is really ing in sadness.

Those in who have not read the History of Clojure paper by Rich really should; great to get a step into Rich's head and to see the evolution of the language. scribd.com/document/470916091/

A great discussion going on here. Because of the location ( thread) there is a bias in the demographic, but good reasons are provided either way and no thoughtless "it's just better" answers. reddit.com/r/Clojure/comments/

Call me crazy, but I sort of love stacktraces. They are so incredibly useful for debugging.

The Beauty of as a language really shone for me yesterday when I was data crawling -- nay, slogging -- through a big multi-type nested blob.

One of the big downsides to being a hosted language like is that, regardless of how awesomely stable the ideology with the language itself, you can't avoid problems if your host decides to make breaking changes. I am still doing damage control on the painful 9+ , where they decided it was time to shrink Java's core library and various dependent packages broke.

I am at a loss in my app. I've loaded a dependency which has cljc code and works fine in other apps of mine. But now when I load it in cljs, it is all nil. Kondo reads it and knows, eg, function signatures for it, but any effort to use it from the repl is just a lot of nil. I have restarted the repl multiple times, but no dice. "type" on any of it, even the NS declaration, is "nil". But Kondo knows it fine. What!?
