Code Golf with JavaScript

quines.js

/* Nodejs Quines */

// everything is wrapped in its own execution context so you can copy + paste the entire snippet without conflicts;
// else, the liberal use of semicolons (and in some instances, the lack thereof) will confuse the interpreter and throw exceptions

// IIFE ES6 quine
{
  (x=_=>console.log(`(x=${x})();`))();
  // 36 bytes

}
// ES6 Quine, shortest I've written thus far
{
  $=_=>console.log(`$=${$};$()`);$()
  // 34 bytes
}
// ES6 Quine writing to stdout
{
  (y=_=>process.stdout.write(`(y=${y})()`))()
  // 43 bytes
}
// Variation
{
  (x=_=>console.log(`(x=${x.toString()})()`))()
  // 46 Bytes
}

// If you have more performant/smaller JS Quines or otherwise suggestions for improvement regarging mine, please do share!
