Noun Extraction: Finding the Ideas

Practice the first step of Abstraction: identifying which concepts in a system are "Ideas" and which are "Actions".

Customer
calculateTax()
Order
Shipment
sendEmail()
printReceipt()
Product
addToCart()

Categorize each item as a Noun (Idea) or Verb (Action).

💡 Abstraction starts by finding the Nouns. If it's a thing the system stores info about, or something that causes action, it's an Idea (Noun).
