## 概述

`name` 属性表示error类型的名称.初始值为"Error".

## 描述

默认情况下,`Error`对象的`name`属性值为"Error".`name属性和` `message`属性一起,通过调用`Error.prototype.toString()`方法,会作为最后异常信息的字符串表示.

## 示例

### 例子: 抛出一个自定义错误

    var e = new Error("Malformed input"); // e.name默认是"Error"

    e.name = "ParseError";                // 修改之后,e.toString()会成为下面这样的字符串
    throw e;                              // "ParseError: Malformed input"
