Write a tiny PostScript interpreter in JavaScript for fun & education

A developer has created a minimal, educational PostScript interpreter in JavaScript. It explores the stack-based language that once powered laser printers and remains at the heart of PDF files.

The project focuses on core concepts like operand stacks, dictionary stacks, and arrays, making this somewhat obscure language accessible for hobbyists. It's a charming, practical exercise in understanding a foundational piece of computing history, proving that building a tiny, understandable interpreter can be more rewarding than just using a full-featured one like Ghostscript.
