从 chrome.storage.sync 中删除数据？

Question

I don't see a remove method in the documentation for removing a specific key. It just has clear()

But it does have a remove for StorageArea for which I don't understand the use case, to begin with.

Answer 1

Storage API has several "backends" that the API calls StorageAreas:

• chrome.storage.local (a single-install-only storage with lax limits)
• chrome.storage.sync (a shared-between-installs storage area with tight limits)
• chrome.storage.managed (a read-only storage populated by policies)

Each is an instance of StorageArea , so each can use any of the described methods .
