The return types of Array and Object detected by typeof are both Object, so arrays and objects cannot be detected using typeof. Therefore, toString encapsulates the type detection function and is convenient to use.

* @description: 数据类型的检测
* @param {any} data 要检测数据类型的变量
* @return {string} type 返回具体的类型名称【小写】
