src/_utils/ 是内部文件，并不对外公开，因此我认为它可能不需要 jsdoc 注释，另外@descCN 标签不属于 JSDoc 范畴。

antd 的 token 有 @descCN 属于给文档用的自定义标签。

考虑到上述原因， 个人感觉这个 PR 的改动不是很重要。

不应该依赖 util 里的方法，不推荐加注释。要加也应该加 @pravite 或 @internal

好的，我不太了解项目的内容，对 JSDoc 也不是很了解，提交了不规范的 PR 很抱歉。
我想先提交一些 JSDoc 来熟悉项目，顺便了解 CI/CD 的流程。我刚刚意识到改动不太准确，我增加了一个新的对外 api 的注释，希望能 review 一下
