I need to check if a string is present in a list, and call a function which accepts a boolean accordingly.

Is it possible to achieve this with a one liner?

The code below is the best I could get:

val strings = List("a", "b", "c")
val myString = "a"

strings.find(x=>x == myString) match {
  case Some(_) => myFunction(true)
  case None => myFunction(false)
}

I'm sure it's possible to do this with less coding, but I don't know how!

Just use contains

myFunction(strings.contains(myString))
