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

I stumbled to this post looking how to apply guards to matches with multiple arguments, it is not really intuitive, so I am adding an random example here.

def func(x: Int, y: Int): String = (x, y) match {
  case (_, 0) | (0, _)  => "Zero"
  case (x, _) if x > -1 => "Positive number"
  case (_, y) if y <  0 => "Negative number"
  case (_, _) => "Could not classify"
}

println(func(10,-1))
println(func(-10,1))
println(func(-10,0))
