Is there a variant of the get function in Clojure, which in a map allows me to retrieve both the key and it’s value ?
Map {:a 1 :b 2 :c}
Give me :b
Returns {:b 2}
I understand I can easily make this myself. Just wondered if such a function is part of Clojure's core. I havn't found it yet.

Love that I’ve been programming Clojure for around 6-7 years, and I can’t recall having seen/used find!
Always some undiscovered gems in clojure.core 😅

Note that find returns a MapEntry, not a vector, although it is printed like a vector. So you can do:
(key (find {:a 5 :b 6} :b))
But not
(key ([:b 6]))
(Same for val of course.)

I've never used find, as far as I remember. 🤔 I should put it on the list of clojure functions to try.

It's pretty hard to find find even with re-find if you're not sure what you want the output to look like. But if you can be a little bit more vague (instead of concrete about the shape of the input/output) ChatGPT gave the right answer

First I asked about something more concrete and it only came up with select-keys
