Japt is a language designed for code-golfing.
Japt is a compiled language, or specifically, transpiled. Many functions have been shortened to a single letter, and there's no need for the dot before or the left-paren after. Input and output are implicit. See the online interpreter for more documentation.
Input is automatically parsed as numbers, strings, and arrays, then stored in various variables.
||Array of inputs|
The last evaluated expression (separated by semicolons) is automatically sent to the output. You can also output by using the functions
Op (the latter prints a trailing newline).
