frappuccino | Functional Reactive Programming in Ruby | Reactive Programming library

I am working on an entry-level project of an automated coffee shop and I ran into a small problem with my code. I have this code if order != "mocha" or "frappuccino" or "cappuccino": in order to filter out selections at the very first choice. But when I try to run my code, the response from the function (yes_or_no_question) also seem to go through the if statement mentioned above and I can not figure out why. I do suspect that it is a problem with the OR operation and strings if not a logical error with the way I have my code set up. I had included my test run errors below, thank you all for your valuable time to help out beginners.

I have a series of products, and I'm trying to set my app up in a way that let's me send someone a link directly to a product. Everything works fine when you try to navigate to a product directly, but if you open that same url directly (without navigating there through the app), it doesn't work.

The issue is coming from subcategoryItems being undefined in the single item view

Router snippet:

I'm trying to access my products based on subcategory title. have I structured my json in a way that makes that impossible?

let data = filename.json gets the file (using Axios). but then data["sub cat title 1"] gets me nothing.

How should I restructure? Thanks

I'm writing a code to practice getters and setters, and I've run into the following situation:

I created 5 products and declared them in a class as private. I want my getter to return the name of the product based on the argument the method receives. Like, public String getProduct(String product) {}. So far, I've written as follows:
