Hi Chuck. Great videos!

I was wondering if you could clear up something.

In LS33S01 you made a modification to type: 'person'. You got rid of the quotes around person. Yet in LS33S02 you made no mention of this even though the quotes were again around person. Code ran fine either way. Does it actually matter?

Hey Chuck. I'm a little confused and hoping you can explain.

I followed your script to the letter and while it works within Scripts - Background, it does not work in VScode nor when running `node c:\path\to\file.js`. It returns "ReferenceError: Class is not defined", pointing at `var Person = Class.create()`

I looked up Class.create() on MDN, but their documentation states to use a constructor to build a class. Can you explain what's going on here? I'm assuming it's some sort of legacy (or otherwise old) JS engine within ServiceNow and Class.create() is no longer accepted in today's JavaScript environment.

Great series, I plan on finishing it very soon.
