final class OrNullOps[A] extends AnyVal

It is common in interop code to model a value as A or null but not undefined even though null and undefined may both mean "absent value." See |.merge Many of these methods are already on js.| but they appear to be left biased as near as I can tell. I'm happy to delete these methods of that's not right and those methods use js.UndefOr in some way.

Note that chaining many js.| together probably not work like you think and sometimes its better to create a new target type then target implicits to convert from each individual type (in the or) to the new target type. You must model your type as A|Null for this implicit to be picked up.

These methods exist to try and stop a conversion to UndefOr or Option as part of null processing. Hey! Every bit counts!

To do

Perhaps the force get methods should throw since .orNull exists in the scalajs standard library now.
