In case you've jumped straight to the comments, here are some intro links. Many of these also appear in ngn/k's readme. First, direct links to ngn/k in the browser: - REPL: https://ngn.bitbucket.io/k/#r - Editor: https://ngn.bitbucket.io/k/ Second, the best one-stop shop for an overview of k6's primitives (both ngn/k and oK are based on k6). https://github.com/JohnEarnest/ok/blob/gh-pages/docs/Manual.... The best intro examples are in John Earnest's k editor iKe - there's a dropdown at the bottom right. http://johnearnest.github.io/ok/ike/ike.html ngn/k's editor also has an 'examples' dropdown in its menu. For an illustration of k's strengths, Razetime's matmul refactoring is brilliant: https://github.com/razetime/ngn-k-tutorial/blob/main/c-think... Finally, some nice examples of concise k: {$[2>#?x;x;,/o'x@&'~:\x<*1?x]} / Quicksort

In K – A simple, fast vector programming language
It was just an honest question. I've just peeked at APL, J and K due to posts here on HN, and the sample code I've seen mostly reads as noise to me, so I was just curious if there were any array languages that would be approachable to me. The tutorial does help a fair bit, though glossing through it, it doesn't really explain why it has to be so exceptionally terse. I mean the matmul[1] sure is impressively short in the end, and with a background in computer graphics and simulations I can absolutely appreciate working on arrays rather than singular values. But I'm sure one could get the same computational result with a bit more approachable syntax. [1]: https://github.com/razetime/ngn-k-tutorial/blob/main/c-think...
