Hey, Bryan! How you doin'?
PureCloud extensibility and customization is all geared for using the API, so one of the scripting languages would be best. You can do research on the internet and come up with all kinds of arguments on both sides regarding whether Python or JavaScript is better to start with.
All I can say, is, our own development teams, testing teams, PS, etc. rely on JavaScript for the most part. Also, when I asked our lead API developer which language/platform I should learn first, he pointed me toward Node.js.
I hope that helps.
