  return path.split('.').reduce((res, key) => res[key] || fb, obj);
}

function parseTpl(template, map, fallback) {
  return template.replace(/\$\{.+?}/g, (match) => {
    const path = match.substr(2, match.length - 3).trim();
    return get(path, map, fallback);
  });

/**
 * 实现一个nodejs的Master-Worker的小程序，要求：
 * 1. Master维护与cpu核数相同的Worker的数量；
 * 2. Master接收到Worker的disconnect消息时，重启新的Worker进程；
 * 3. Worker监听1024端口并输出“Hello World”；
 * 4. 在Worker遇到uncaughtException时，通知Master进程并等待3s后退出
