Analyze most frequent word program

Analysis

/* After removing any falsey items from the raw text using the getTokens function, we are left with one clean 
lower case string containing only words seperated by spaces. The mostFrequentWord function takes that string
and assigns it to a variable, words. The function then iterates through each word and if it encounters a new
word it adds one to a new key in an object, wordFrequencies. If it has already encountered the word, it adds
one to the key at which it first encountered the word.

Afterwards, it sets a variable, currentMaxKey, to the first word in the wordFrequencies object and another
variable, currentMaxCount, to whatever index of the currentMaxKey in the wordFrequencies object.

Next the function iterates over every property in the wordFrequencies object. It then runs an if statement
stating if the current iteration in the object is greater than the currentMaxCount variable, it sets the
currentMaxKey as the value at the current iteration and the currentMaxCount at the iteration number itself.
Once it runs through the entire string, it returns the currentMaxKey, thus giving us the word that has
been found the most. */
