Avoid ImmutableJS Map converting arrays to List

Question

Curently if I have m.set(someArray) where m is a Map, it will try to convert someArray to Immutable List. How do I disable this behaviour?

Answer 1

Pass a copy of the array, instead:

m.set(someArray.slice());

Note that, if the array contains reference values (objects, arrays), the references are copied. .slice() is only a shallow copy.
