IIFEs + exporting node modules = overkill!

[minaorangina]

Let's take handler.js for example.

You are wrapping everything in an IIFE (immediately-invoked function expression) and exporting that IIFE into your index.js.

IIFEs are great for privacy in the frontend, but not necessary here. When exporting/requiring modules, anything that's left behind is automatically private.

Think of it as locking your code in a vault, then putting your vault in another vault, then dropping that vault in the sea with a ball-and-chain attached, before adding another vault. Overkill. :wink:

Ok thanks Mina, that helps with the understanding of why we need IIFEs! Really useful
