-### Set localStorage
-
-This API is similar to the browser's `localStorage.setItem`, but the setting parameter is the entire JSON-formatted data instead of a single key-value pair.
-
-When developing front-end extensions, you should avoid using the browser's `localStorage`, because using the browser's `localStorage` directly will cause data to be incorrectly overwritten or lost when switching between multiple workspaces.

-### 设置 localStorage
-
-该 API 类似浏览器的 `localStorage.setItem`，但是设置参数是整个 JSON 格式的数据，而不是单个键值对。
-
-前端开发扩展时应该避免使用浏览器的 `localStorage`，因为直接使用浏览器的 `localStorage` 会导致多工作空间切换时数据错误覆盖或丢失。
