	return rawString.toLowerCase().split(/[ ,!.";:-]+/).filter(Boolean).sort();
	//split() splits the paragraph into words using regular expression
	}

	var words = getTokens(text); //use getTokens to get an array of words from the paragraoh text
	var wordFrequencies = {}; //defing an object to save frequency of every word
	for (var i = 0; i <= words.length; i++) { //loop to iterate through the array of words
