What is string interpolation in Perl?

String interpolation in Perl refers to the process of embedding variable values directly within double-quoted strings or certain other types of strings. This allows for more readable code, as variables can be incorporated seamlessly without needing to concatenate strings explicitly.

For example, using string interpolation with double quotes, we can easily embed variable values:

my $name = "John"; my $greeting = "Hello, $name!"; print $greeting; # This will output: Hello, John!
