Repeat strings with the repetition operator Repeat strings with the repetition operator
You get the idea - Perl has a repetition operator (x) that repeats the scalar or list on its left by the number on it’s right (like multiplication).
my $string = 'I like chocolate';
print $string x 10;
#results
I like chocolateI like chocolateI like chocolateI like chocolateI like chocolateI like chocolateI like chocolateI like chocolateI like chocolateI like chocolate
You may be able to think of more useful employment for this operator, like this:
perl -CS -e 'print qq!\N{U+2661} \N{U+2665}! x 1000;'
