clarification: imports from path/to/module !?

In the summary of the [import-export chapter](https://javascript.info/import-export#summary) they use `... from "module"`.
Wouldn't it be more correct to write `... from "path/to/module"` or something like that?
Isn't that the essential point of `export`/`import ... from ...` - that it requires a relative/absolute path and not just a file name?!

从 import-export 章节中链接的 Summary 部分开始，将其中的 `... from "module"` 示例与该章节对模块路径的说明进行比较。完成的标准是：Summary 准确澄清导入是否需要相对路径或绝对路径，且不与周围的教程内容矛盾。
