// Directly injecting in Array prototype so function is avialbale to all array.
// mapFunctionPolyFill is name of the function 
// i just assign function that provider own implemention of map function
// cb is a callback function that will execute against the each array element
Array.prototype.filterFunctionPolyFill = function (cb) {
  const output = [];// store the result of cb function
  const arrLength = this.length; // length of the array in which cb function is called
  // we need to call cb function for each element in array
  for (let i = 0; i < arrLength; i++) {
    // same as inbuilt filter function our map function had 3 parameters
