Return

Exit the current scope, which can be a function, script, or script block.

Syntax
      return
      return expression

In PowerShell, the result of each statement is returned as output, even without an explicit Return keyword.

So
 $price
 return
has exactly the same effect as:
 return $price

Examples

Add the number 5 and return the value:

function demoadd {
   param ($value)

   "Adding five"
   $value += 5
   return $value
   }

PS C:\> $result = demoadd 2
PS C:\>
PS C:\> $result
Adding five
7

The key point to note in the above example is that the "Adding 5" string is not displayed, but is instead assigned to the $result variable and returned along with the number.
