Error 类
通用的 JavaScript <Error> 对象,不表明错误发生的具体情况。
Error
对象会捕获堆栈跟踪,详细说明实例化 Error
的代码点,并可能提供错误的文本描述。
Node.js 产生的所有错误(包括所有的系统错误和 JavaScript 错误),都实例化自或继承自 Error
类。
A generic JavaScript <Error> object that does not denote any specific
circumstance of why the error occurred. Error
objects capture a "stack trace"
detailing the point in the code at which the Error
was instantiated, and may
provide a text description of the error.
All errors generated by Node.js, including all system and JavaScript errors,
will either be instances of, or inherit from, the Error
class.
