(async ()=>{

  // 创建 safeify 实例
  const safeVm = new Safeify({
    timeout: 3000,
    asyncTimeout: 60000
  });

  // 定义 context
  const context = {
    a: 1,
    b: 2,
    system: {
      add(a: number, b: number) {
        return (a + b) * 2;
      }
    }
  };

  // 执行动态代码
  const result= await safeVm.run(`return system.add(1,2)`, context);
  console.log('result', result);

  // 释放资源
  safeVm.destroy();
  
})();
