Uiua's many built-in functions allow you to easily express complex data transformations.
Write concise, point-free code through tacit programming.
Uiua has very simple syntax and thus little ceremony.
All built-in functions have friendly glyphs. The formatter auto-converts function names into glyphs.
Uiua uses a simple, stack-based execution model that executes code from right to left.
Every language has its own way of doing things. Uiua is no different. Our mentors will help you learn to think like a Uiua developer and how to write idiomatic code in Uiua. Once you've solved an exercise, submit it to our volunteer team, and they'll give you hints, ideas, and feedback on how to make it feel more like what you'd normally see in Uiua - they'll help you discover the things you don't know that you don't know.
