Description Yusuke Suzuki 2015-06-08 11:50:02 PDT
For example, BooleanPrototype, DatePrototype, ErrorPrototype, FunctionPrototype etc. do not have `vm.prototypeMap.addPrototype(this)` setting phase.
Comment 1 Geoffrey Garen 2015-06-08 12:39:06 PDT
Maybe we should move the responsibility for declaring prototypes into the Structure finishCreation function. That way, we're guaranteed to know about all prototypes.

Who calls addPrototype for DOM prototypes?
Comment 2 Yusuke Suzuki 2018-05-05 01:29:11 PDT
prototypeMap is removed from the tree.

> prototypeMap is removed from the tree.

That doesn't remove the need to set their isPrototype bit.
