You’ve already seen it mentioned a few times, but in case it wasn’t clear, I’m proposing the term “Immediately-Invoked Function Expression”, and “IIFE” if you like acronyms. The pronunciation “iffy” was suggested to me, and I like it, so let’s go with that. What is an Immediately-Invoked Function Expression? It’s a function expression that gets invoked immediately. Just like the name would lead you to believe.
