  Hi,

  I'm kind of confused/lost when to use one form vs the other when defining parameters in a function.

  f.ex.

  1) param() defined in the function

  function get-total-1() {
      param([int] $a, [int] $b)
      return $a+$b
  };

  2) param as a function signature 

  function get-total-2([int] $a, [int] $b){
      return $a+$b
  };

  When should you use get-total-1 vs get-total-2 parameter form in a function?

  Or is there any reason to prioritize one form vs the other ?

  Thanks a lot for helping me clarifying this (problem).

  Kind regards,

  Didier
