Basically it is to parse, or not to parse. :)
If we have a scalar variable called $foo which is defined as:
my $foo = 'is really cool.';
And we want to print it out using both methods as such:
print "1 -- This $foo\n";
print '2 -- This $foo\n';
Will produce the following:
1 -- This is really cool.
2 -- This $foo\n
If you have variables or special characters ( i.e. \n, \t, etc )
in a string enclosed by ""s then they will be replaced with their
values. If you have them enclosed in ''s they will be used
literally.
Hope that helps.
