Why after updating Array element I still get old array values?

Why after updating Array element I still get old array values?



var compactWay = Array("I", "like", "this", "way")

>compactWay: Array[String] = Array(I, like, this, way)


compactWay(0) = "We"

println(compactWay.mkString(" "))

>We like this way res3: Unit = ()


var secondList = Array("Something else")

var thirdList = compactWay++secondList

>thirdList: Array[String] = Array(I, like, this, way, Something else)

(expecting to see Array(We, like, this, way, Something else)
