Tiny language playground

Explore variables and arithmetic in a small local interpreter.

How it works and limits

One statement per line: let name = expression, print expression, or # comment. Expressions support numbers, existing variables, +, −, *, / and parentheses. No loops, functions, JavaScript, files or network. At most 100 lines and 2,000 tokens. Output is plain text.

Worked example

source: let price = 25
let count = 4
print price * count
print (price + 5) / 2

Inputs start empty. Load example fills them only when you choose it. Reset clears inputs and results.
