By a true quine I mean a real true quine. Maybe the wikipedia article of quine will help:
A quine is a computer program that takes no input and produces a copy of its own source code as its only output. The standard terms for these programs in the computability theory and computer science literature are "self-replicating programs", "self-reproducing programs", and "self-copying programs".
So no evals or reading the source like this:
function quine() { console.log(quine.toString()+" quine();") } quine();
Can you do it?
The wikipedia article contains a Java Quine If you need a hint
