Does Scala have guards?

Question

I started learning scala a few days ago and when learning it, I am comparing it with other functional programming languages like (Haskell, Erlang) which I had some familiari

Answer 1

The simple answer is no. It is not exactly what you are looking for (an exact match for Haskell syntax). You would use Scala's "match" statement with a guard, and supply a wild card, like:

num match {
    case 0 => "Zero"
    case n if n > -1 =>"Positive number"
    case _ => "Negative number"
}
