How to know if an object was created by Immutable

Question

I need to detect if an object is some kind of Immutable or not. How do I do this?

Lots of good info in this thread: http://stackoverflow.com/questions/31907470/how-to-check-if-object-is-immutable Note that `isIterable` returns false for the `Record` type. — VanDanic, Jan 25 '17 at 08:23

Doesn't look like they've gotten around to making a cleaner API for this, but for now you can use Immutable.Iterable.isIterable() to check if something is an iterable immutable collection.

You can use Iterable.isIterable

Immutable.Iterable.isIterable(Immutable.Map()); // true
Immutable.Iterable.isIterable({}); // false
