Example output :
PS C:\Users\alex\Documents\code\node\practice\weekone> node .\main.js
old school : An exclusive barrel-aged blend, brought together to reward investors on Equity for Punks USA; two imperial stouts aged in grain whisky barrels for over a year.
new school : Cloudberry, lingonberry, blueberry and sea buckthorn meld with citrusy hops in an intensely sweet, fruity and floral aroma, with toasty malt notes and tropical fruit bursts. This bitter, resinous IPA follows up with a lemony punch in the mouth - cherry and blueberry sourness takes this pithy pale ale in a new direction before a long, dry finish.
