ngn/k has a hidden, somewhat secret data structure: the table. Tables are a prominent presence in k7 and k9, the latest versions of K, so ngn/k supports them for that reason.
A table uses symbols to mark columns, and integer indices to mark rows. Making a table is simple. The first method is flipping a dictionary1:

The language, all names, characters, and incidents portrayed in this production are fictitious. No identification with actual languages (living or deceased), places, buildings, and products is intended or should be inferred.
The language is called APL (asinine programming language), and it will be on the esolangs wiki under APL (esolang), probably mentioned under APL (disambiguation).
Functions are defined using ∇name (⍵,⍺) <stuff here> .. the (⍵,⍺) portion will always remain the same and cannot be changed.
Only two arguments can be given to a function.
All assignments are by reference.

Welcome to K. K is an array-based programming language. Although this term may sound new to many programmers, K comes from a lineage of programming languages which date back to the 1960s.
It is the 1960s. Enter APL. APL originally started out as a general math notation, made to standardise the way mathematical expressions can be looked at. With the creation of APL's revolutionary math notation came the realization that it was very effective at describing algorithms, making it very effective with consistently communicating algorithmic, math-oriented thought. This original award winning idea eventually became what is known today as the APL programming language.
Array languages to this day are still a rather niche area, since they are very unlike what people are taught as beginner programmers. Hence, I'd like to request all viewers to maintain an open mind and have fun.
K is an APL-style array language which aims to eliminate many of APL's problems in programming. At a glance, the most noticeabl
