TypeError 类

• 继承自 <errors.Error>

表明提供的参数不是被允许的类型。 例如，将函数传给期望字符串的参数，将会被视为 TypeError。

require('url').parse(() => { });
// 抛出 TypeError，因为它期望的是字符串。

Node.js 将会以参数验证的形式立即地生成并抛出 TypeError 实例。

• Extends <errors.Error>

Indicates that a provided argument is not an allowable type. For example, passing a function to a parameter which expects a string would be considered a TypeError.

require('url').parse(() => { });
// Throws TypeError, since it expected a string.

Node.js will generate and throw TypeError instances immediately as a form of argument validation.
