The purpose of this article is to explain when the different JSObject methods are called during script execution and in some cases how they should be implemented.

I just learned something about pattern matching and case objects in Scala which I thought I’d share.

In this post, I’m going to demonstrate how to get a useful diff for binary Excel files that reside in a Git repository.
