How to remove duplicates from an unordered Immutable.List()?

Question

How would one remove duplicates from an unordered Immutable.List()? (without using toJS() or toArray())

e.g.

Immutable.List.of("green", "blue","green","black", "blue") 

Answer 1

You can convert it to a Set. A Set is a List with unique values.

Immutable.List.of("green", "blue","green","black", "blue").toSet() 

If you need it as list again just convert it back then:

Immutable.List.of("green", "blue","green","black", "blue").toSet().toList() 

Update:

It exists a shorter possibility to get unique values:

Immutable.List.of("green", "blue","green","black", "blue").distinct
