A Javascript application which takes a book as an input text file and outputs how many times each word occurs in the book. It also displays whether the number of occurrences for each word is a prime number or not.

The application ignores irrelevant punctuation and capitalisation.
'Question' and 'Question?' are both counted as the same word.
'The' and 'the' are both counted as the same word.
"don't" is counted as a single word.
'mother-in-law' is counted as a single word.
