Simple nodeJS function to crash with a stackoverflow

stackoverflow.js

/* This program will use a recursion to provoke a stackoverflow
   use it at your own risk. It might take more than the runtime down.
*/

const looper = function(instanceCount) {
  console.log(
    `Calling instance ${instanceCount} with ${process.memoryUsage().heapUsed}`
  );
  var body = '';
  for (var i = 0; i < 1000000; i++) {
    body += 'Big fat body, big fat body, really big and fat\n';
  }
  instanceCount++;
  looper(instanceCount);
  // Need to use body after the recursion to avoid tail
  // optimization that just would recycle body
  // It never gets executed
  console.log(`String size is ${body.length}`);
};

// Event loop to stop if we panic
const stdin = process.stdin;
console.log('Press the famous anykey to stop the madness');
stdin.resume();
stdin.on('data', d => {
  console.log('Good bye!');
  process.exit();
});

// Start the whole mess
looper(0);
