Experience
App.js
It's a high-level application using JavaScript 1.4 that allows the simulation of a relational model object.
The big challenge here is using JavaScript for Google scripts. We can't use dependencies in these types of implementations, so this is a high-level implementation of a relational model for spreadsheets.
Some application implementation is required for our users.
