JavaScript Classes Lab

Intro

Now that you've learned about using classes in JavaScript to create objects, it's time for some practice!
In this lab, you will choose one of the object hierarchies below, Bank Accounts or People, and write the classes to implement it.

Setup

Create a JavaScript REPL from repl.it -- you can name it "JavaScript Classes Lab".`
