'''K''' denotes a family of programming languages designed by [[Arthur Whitney]] | '''K''' denotes a family of programming languages designed by [[Arthur Whitney]], which is sold by Kx Systems and Shakti and also supported by several independent implementations. K is an ASCII-only language influenced by Whitney's previous APL design [[A+]]. It has fewer primitives in part because it represents arrays as [[list model|nested lists]], unifying [[rank]] and [[depth]], and encourages [[wikipedia:Scheme_(programming_language)|Scheme]]-like functional programming with [[wikipedia:first-class function|first-class function]]s. Whitney presented the first K implementation (K0) in 1992, and soon founded [[Kx Systems]] to develop it further with versions numbering K1 through K6. K4 is now the implementation language for the time-series database kdb+ as well as derivative language [[Q]]. Whitney has developed further versions of K at Shakti, beginning with K7. Notable non-commercial implementations include [[Kona]] based on K3, and [[ngn/k]] and [[oK]] based on K6. | ||
