Why APL

four things that make it yours

Variables

Define int, double, bool and string — plain keywords, no boilerplate.

Loops

Loop until a condition is false — written exactly like you'd say it aloud.

Functions

Define with func, call with call — reuse any block of code you write.

User Input

Read from the keyboard into any variable — one letter, r x, and you're done.

How it works

from a chalk line to an answer, in four steps

Code
v int x = 5
Lexer
splits into tokens
Interpreter
walks the tree
Output
5
