Replace String with array indexes with Array elements using Regex. Jquery

Question

I need an string helper to replace everything within the square brackets with variables. using javascript

"Hello, [0]".modify(["ABC"])

"Heelo, [0], This is [1]".modify(["ABC", "XYZ"])

"Heelo, [0], This is [1], Your email address is [2]".modify(["ABC", "XYZ", "abcdef@example.com"])

So basically the modify() will take the array and replace the string with appropriate indexs.

Any advice would be helpful.

String.prototype.modify = function(arr) {
    return this.replace(/\[(\d+)\]/g, function(c, m) {
        return arr[m] === undefined ? c : arr[m];
    });
};

"Heelo, [0], This is [1]".modify(["ABC", "XYZ"]);
// "Heelo, ABC, This is XYZ"

String.prototype.modify = function() {
  var s = arguments[0];
  for (var i = 0; i < arguments.length - 1; i++) {       
    var reg = new RegExp("\\[" + i + "\\]", "gm");             
    s = s.replace(reg, arguments[i + 1]);
  }
  return s;
}
