Charcoal

Expressions are automatically printed without explicit commands, as shown where 'foo' directly outputs 'foo', simplifying code for quick sketching.

Uses arrows like ↖ to dynamically change printing direction, enabling complex ASCII patterns such as diagonal lines, as demonstrated in the examples.

Provides a real-time environment for experimenting with ASCII art, allowing immediate feedback and iteration without compiling or saving files.

Relies on simple literals and superscript numbers, reducing the learning curve for basic ASCII art creation, as seen with strings like 'foo' and numbers like ¹²³⁴.
