> ## Welcome Back to Mastering Google Apps Script UIs: Client-to-Server Communication Spotlight
> 
> 
> Oh, howdy folks! Just like a boomerang, you’ve found your way back to our marvelous series. If you thought the previous episodes were fire, wait till you see what’s cooking today! 🔥
> We’re diving headfirst into the world of client-to-server communication. It’s like passing notes in class, but with a lot less paper and a lot more code. 📝➡️💻
> Here’s the catch though — we can’t install Google Apps Script locally to run things on our dev server. Yep, that’s right. It’s like trying to install a toaster in a bathtub; it just ain’t happening. 🛁🚫🍞
> But fear not, dear coder, for I’ve got a trick or two up my sleeve. We’re gonna finesse our way around this with some snazzy hacks like promises, polyfills, and mocks. Oh my!
