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

this is how you can call a function and get the result by the helps of Array() and join()

function repeatStringNumTimes(str, num) {
  // repeat after me
  return num > 0 ? Array(num+1).join(str) : "";
}

console.log(repeatStringNumTimes("a",10))
