Language Reference - Operators - Operator !== (Strict Tests If Two Values Are Not Equal (Case Sensitive))

Operator !==

Tests if two values are not equal and not the same type (case sensitive if used with strings). e.g.

//define variables..  
my $str = "9";  
my $int = 9;  
//Returns false since both variable contains the same value..  
my $res = ($str!=$int); 
say "Str '9' != Int 9; " . ($res ? "True" : "False"); 
//Returns true since the two variables are not of the same type..  
my $res = ($str!==$int);
say "Str '9' !== Int 9; " . ($res ? "True" : "False");
