How to compare a value to several other values in one line in Kotlin

Question

Is there a better alternative to this expression in Kotlin: a == b || a == c

I'm looking for something like a == b || c or a.equals(b, c)

Answer 1

I think the simplest way is with the in operator:

a in listOf(b, c)

you can include as many items as you want inside the list.
