You can change the directory.

BQN is a newer array based language (similar to APL) where you manipulate arrays with different functions and modifiers and compose the modifiers with more modifiers (combinators). Uiua is the same but instead of combinatorics you have a stack that you can manipulate, so it’s a stack based, array oriented language. Here is a nice video about Uiua, and here is a video comparing the two.

To add to others’ responses, array-based languages such as APL, BQN and J are very different from most common languages
