Uiua

Uiua is a stack-based array-oriented programming language created by Kai Schmidt (He/Him). It uses an APL right-to-left top-to-bottom evaluation scheme. Like other array languages, the only composite data type is multidimensional rank-polymorphic arrays. Operations can be applied to the whole array without needing explicit flow-control. Unlike other array languages, Uiua does not have different monadic and dyadic behaviors for each glyph. Finally, Uiua features a Unicode formatter that gives ASCII names to its glyphs which can assist in writing code.

Additionally, the language has out-of-the-box support for rendering an array as an image or playing an array as audio.

Uiua's website features an interactive playground, documentation, examples, and notes about it's design. Its Rust source code is hosted on Github.
