  // Initialize context based on: -Xms, -Xmx, -XX flags, GC logging, heap size tuning
  const context = setupContext();
  
  // Execute core logic
  executeLogic(context);
}

function executeLogic(ctx) {
  // This represents the production-ready implementation 
  // of the concepts discussed in this chapter.
  return true;
}
