When should you prefer string interpolation, and when should you avoid it?

String interpolation in Perl can make your code cleaner and more readable but may introduce issues in certain situations. It's preferable when working with simple variables and when readability is essential. However, avoid it when dealing with complex expressions, special characters, or when exact string representation is important.

# Example of string interpolation my $name = "John"; my $greeting = "Hello, $name!"; print $greeting; # Outputs: Hello, John! # When to avoid string interpolation my $amount = 100; my $message = "Your total is \$${amount}."; # Best to escape $ print $message; # Outputs: Your total is $100.
