Answer 1

use this trimRight method: https://www.sitepoint.com/trimming-strings-in-javascript/

String.prototype.trimRight = function(charlist) {
  if (charlist === undefined)
    charlist = "\s";

  return this.replace(new RegExp("[" + charlist + "]+$"), "");
};

console.log("01,02,03,,,".trimRight(','));

Answer 2

var input = "01,02,03,,,,";
//Keep checking if the trailing character is ','
while(input && input.charAt(input.length-1) == ","){
  //if true trim the last character and continue
  input = input.substring(0,input.length-1);
}
console.log(input);
