Using Design Patterns in Google Apps Script – Introduction to façade and proxy patterns

A lot of users try and quickly learn GAS and use it to make their lives easier. It’s all great, however the code we sometimes tend to come across on StackOverflow and other sites lacks best practices, hence I thought it was time to start bringing them up and I will start today with design patterns.

As noted by the post author Dmitry Kostyuk the Google Apps Script V8 runtime opens up many new coding opportunities previously not available to Apps Script developers. Using the common use case, fetching data and writing it to a Google Sheet, Dmitry explains how the façade and proxy code patterns can be used to write efficient easy-to-read code.
