'h' x n;

Here n is a variable, and the generated string should be n times duplicate of h:

hh..h( n occurance of h in all)

Answer 1

Here's a cute way to do it with no looping:

var n = 20;
var result = Array(n+1).join('h');

It creates an empty array of a certain length and then joins all the empty elements of the array putting your desired character between the empty elements - thus ending up with a string of all the same character n long.

Answer 2

String.prototype.repeat = function(n){
  var n = n || 0, s = '', i;
  for (i = 0; i < n; i++){
    s += this;
  }
  return s;
}

"h".repeat(5) // output: "hhhhh"

Something like that perhaps?

Answer 3

If I understood your question following may be the solution.

var n = 10;
var retStr = "";
for(var i=0; i<n; ++i) {
retStr += "h";
}

return retStr;

Answer 4

Try,

function repeat(h, n) {
    var result = h;
    for (var i = 1; i < n; i++)
       result += h;
    return result;
}
