A javascript application that counts occurrences of words in a .txt file and outputs the resultant hash including whether the number of occurrences is a prime number.
As a user,
so that I can see the number of times a word appears in a txt file,
I want to be able to output the individual words and how many times it appears.
As a user,
Because I am curious, I would like to see if the occurrences of the words are prime numbers,
that is, if the number is divisible by only itself and 1.
First I created an Array and populated it with the individual words in a string. Next I changed the split method to ignore whitespace. Then I again changed the split method to ignore punctuation. When I was sure that I was populating the Array with just words I implemented a function to count the occurrences and add the results to a Hash.
The second part of the exercise was to determine if the occurrences were primes, I then added this information to the Hash in the form of a boolean.
Until this point I had written the application in VanillaJS but had to add the Node 'require' module to read from a text file, this was unforeseen and was what I found most challenging.
