Setup

var format = "{container_id}-{client_id}-{vu_id}-{iteration_id}";

var CONTAINER_ID = "CONTAINER_ID";
var rpiclient_id = "rpiclient_id";
var execvuidInInstance = "execvuidInInstance";
var execvuiterationInInstance = "execvuiterationInInstance";
var scopes = ["email", "profile", "openid"].join("_")

var obj = {
  container_id: CONTAINER_ID,
  client_id: rpiclient_id,
  vu_id: execvuidInInstance,
  iteration_id: execvuiterationInInstance,
  scopes: scopes,
};

function replaceMutiple(str) {
  return str
    .replace("{container_id}", CONTAINER_ID)
    .replace("{client_id}", rpiclient_id)
    .replace("{vu_id}", execvuidInInstance)
    .replace("{iteration_id}", execvuiterationInInstance)
    .replace("{scopes}", scopes);
}

function replaceRegex(str) {
  return str
    .replace(/\{([a-zA-Z_]+)\}/g, (match, token) => {
      return obj[token] || "";
    });
}

function replaceWhile(str) {
  var outstr = "",
    start = -1,
    end = 0;
  while ((end = str.indexOf("{", ++start)) > -1) {
    outstr += str.slice(start, end);
    start = end;
    if ((end = str.indexOf("}", start)) > -1) {
      outstr += (obj[str.slice(start + 1, end)] || "");
