Repeat Character N Times

Question

In Perl I can repeat a character multiple times using the syntax:

$a = \"a\" x 10; // results in \"aaaaaaaaaa\"

Is there a simple way to ac

Answer 1

Can be used as a one-liner too:

function repeat(str, len) {
    while (str.length < len) str += str.substr(0, len-str.length);
    return str;
}
