示例：已修补的依赖

【Example: Patched dependency】

重定向的依赖可以根据应用的需要提供减弱或修改后的功能。例如，通过封装原始函数来记录函数持续时间的日志数据：

【Redirected dependencies can provide attenuated or modified functionality as fits the application. For example, log data about timing of function durations by wrapping the original:】

const original = require('fn');
module.exports = function fn(...args) {
  console.time();
  try {
    return new.target ?
      Reflect.construct(original, args) :
      Reflect.apply(original, this, args);
  } finally {
    console.timeEnd();
  }
}; 拷贝
