//core method to handle execution
//has two arguments one is Array of methods that has to execute
//second param is enabling step by step execution.
function makeexecution(methodsArray, isStepbystep) {
  //creating promise Object to return
  var promise = {};
  //method to execute steps one by one If isStepbystep flag is set as true
  //It uses to execute array of methods in synchronous manner.
  function executeNextMethod(methodsArray, methodIndex, callback) {
    if (methodsArray.length === methodIndex) {
