Kiukiujs

Kiukiujs is a fictional programming language used in computer science education and speculative discussions to illustrate language design concepts. It is not defined by an official specification, and there is no canonical implementation. In descriptions found in tutorials and forum posts, Kiukiujs is presented as a small, dynamically typed, prototype-based language with garbage collection and first-class functions. Proponents emphasize a balance between readability and expressive power, drawing on influences from JavaScript and other prototype-based languages, while proposing a minimal core syntax intended to be approachable for beginners.

Design and features commonly attributed to Kiukiujs include a concise syntax reminiscent of JavaScript, support for functions as values, lexical scoping with closures, and a simple module system. Some descriptions imagine optional typing or a lightweight standard library, but these are not standardized across sources. The language is typically characterized as a teaching tool rather than a production-ready option.

Origin and usage: The term Kiukiujs appears in online communities as a placeholder name for experiments in parser design, language features, or compiler demos. There is no official body maintaining it, and any concrete interpreters or playgrounds are informal, hobbyist projects. In education, Kiukiujs is used to compare language paradigms, discuss trade-offs between dynamic typing and static typing, and illustrate interpreter implementation concepts.

Etymology: The name is informal, with no formal etymology established in sources.
