Kotlin - Idiomatic way to check array contains value
What's an idiomatic way to check if an array of strings contains a value in Kotlin? Just like ruby's #include?.
I thought about:
array.filter { it == "value" }.any()
Is there a better way?
Answer
The equivalent you are looking for is the contains operator.
array.contains("value")
Kotlin offer an alternative infix notation for this operator:
"value" in array
It's the same function called behind the scene, but since infix notation isn't found in Java we could say that in is the most idiomatic way.
