You have:
val array = new Array[Array[Cell]](height, width)
How do you initialize all elements to new Cell("something")?
Thanks, Etam (new to Scala).

Create Array with RangeUse of range() method to generate an array containing a sequence of increasing integers in a given range. You can use final argument as step to create the sequence; if you do not use final argument, then step would be assumed as 1.
Scala arrays can be generic. which mean we can have an Array[T], where T is a type parameter or abstract type. Scala arrays are compatible with Scala sequences – we can pass an Array[T] where a Seq[T] is required. Scala arrays also support all sequence operations.
