Move list of adjectives into its own file

[uwaseem]

Right now, the list of adjectives sits in index.js.
This is fine for now, but as the list grows, the file itself will become clunky.
To keep things clean and readable, it might be worth moving the list into its own file.

I'd like to create a new dir to store these data.

Hi, I'm able to successfully apply the changes.. Also, I suggest a new function for getRandomNumber function as your one is not working as expected. Thank you
