语法
@license <标识符>
概述
@license 标记标识适用于代码任何部分的软件许可证。
你可以使用任何文本来标识你正在使用的许可证。如果你的代码使用标准的开源许可证，请考虑使用 软件包数据交换 (SPDX) 许可证列表 中的适当标识符。
一些 JavaScript 处理工具（如 Google 的 Closure Compiler）将自动保留任何包含 @license 标记的 JSDoc 注释。如果你正在使用其中一种工具，你可能希望添加一个包含 @license 标记的独立 JSDoc 注释，以及许可证的全部文本，以便许可证文本将包含在生成的 JavaScript 文件中。
示例
/**
* Utility functions for the foo package.
* @module foo/util
* @license Apache-2.0
