It depends on the likelihood that the value was created in a different realm. For keys and values coming straight out of
IndexedDBit doesn’t matter - as we know they come from the current realm (whereIndexedDBand the structured clone algorithm lives).It pretty much only matters for user input. When a user does
db.get(date), that date key might have come from a different realm.@vweevers Are there any rules on when it is important and not important, e.g. why isn’t instanceof in the constructor and the Uint8Array important?
