let stack = require("https://gist.github.com/khaled0fares/4ffe7a9db1c4c71b1e361c2c636f0c71");// Link to the stack gist, for calirfication only.

let isPalindrome =  function(txt){

  let len  = txt.length, 
    stack = new Stack(len), 
    reversed =  "",
    i = 0;

  while(!stack.full()){
    stack.push(txt[i]);
    ++i
  }

  while(!stack.empty()){
    reversed += stack.peek(); // Get top element in the stack.
    stack.pop();
  }
  
  return txt === reversed;
}

console.log(isPalindrome("1001"));// true
