Hello @v8js
Does Object.create() always create dictionary-mode objects? Or is it only the special case of Object.create(null) that triggers it?

I can observe the opposite; Date: DictionaryProperties (same as O.c(null)) and O.c(Date): FastProperties.

Isn’t that what Rob was saying (i.e. not the opposite)? %DebugPrint helps. I don’t know about any other cases that trigger DictionaryProperties. Maybe

Yes, `Object.create(null)` always creates dictionary-mode objects. Object.create(prototype) tries hard to create fast-mode objects.

I like the way that tweeting
@v8js is a bat-signal call-to-action for the underlying team. Maybe I should try it with@horse_js and see who responds

They have an OKR with alerts that fire when someone tweets at them. AFAIK they alert after 5min with no response via an automatic bug filed, and then after an hour it pages the oncall. Then I think Sundar's phone rings after 2 hours.

After 4 hours, a bot starts deleting a random line of code from the V8 repository every 15 minutes.
