Nebbish

X01[:}+ix=b]; A program to calculate the nth Fibonacci number.

[[ij*P84*pj9=b]Ni9=b] A program to show a times table.

Overview

Nebbish is a stack-based golf language that uses one printable ASCII character per command. Unlike say, a language like Vyxal, with a command for everything, Nebbish aims to provide a modest set of primitives that combine to tackle golf-style problems orthagonally. The primary goal of the language is to make terse procedural code fun to write. Terseness itself is secondary.
