Question

I have 2 questions:

1. Suppose if i have a string "Have a nice day"
   this is the output I want: " " (15 spaces)

2. Also how do you create a string dynamically in javascript
   For eg: in ruby

   "A"*10
"AAAAAAAAAA"

If the latter is possible I could have done the first one ( something like this. ) " "*(input.length)

Answer 1

Ans for Q1:

var str = "Have a nice day";
str = str.replace(/./g, ' ');

Ans for Q2:

String.prototype.repeat = function(n) {
  return new Array(n+ 1).join(this);
};

"A".repeat(10);
