First function getTokens tells me that it takes the rawstring that is the string
(a paragraph) in raw form and what this function does is that it lowercase the string
cut downs into a group(array) by splitting it with various factor and filter out and sort them in 
ascending order.

Next Function MostFrequentWord takes text as input and the first lines does it what i
written about on the function. it defines the object wordfrequencies which would take the 
all the words occurring in the array and whenever it finds one it increases the count of
the word.

// running the function with `objectA` and `expectedKeys`
// should return `true`
var objectA = {
  id: 2,
  name: 'Jane Doe',
  age: 34,
  city: 'Chicago'
}

// running the function with `objectA` and `expectedKeys`

function createMyObject() {
  // your code here
  
  return {'foo':'bar','answerToUniverse':42,'olly olly':'oxen free','sayHello':function () {return 'hello'}};
}

What is scope?
Scope is what we say something that is only accessible to the current block. so when we say a global scope that says us that this would accessible throughtout the code while local scope would be accessible to the only block where it was defined.

Why are global variables avoided?
Main reason behind the avoiding the global variables is that when in need of the updated global variable it might not be one we're looking for.

Explain JavaScript's strict mode.
Strict Mode is use so that the code throws more exceptions and certain actions are also prevented from doing stuff they are meant to do.

What are side effects, and what is a pure function?
