I suppose I should have been more specific:
This is an error foo():
function () {} ()
This is not (foo)()
(function () {})()
This is not (foo())
(function () {}())
So foo() is NOT identical to (foo)() where foo is function () {}.

var foo = function () {};
foo gets hoisted
function foo() {};
foo gets hoisted
for () {
x = function () { console.log(i) };
}
What actually happens is this
function something() {console.log};
for () {
x = something;
}
I probably could word that better since that's not technically "hoisting",
but in essence it's still hoisting. The creation of the function is pulled
out of the loop in the same way `var x` would get pulled out and only the
reference remains.
Also setTimeout() takes optional parameters to pass to the callback:

Well, duh. Anyone with years of JavaScript experience knows that!
However, years of wretched online tutorials do not. I agree that it's a
good solution (and I should probably show that as an alternate way to do
it. However, a common solution is to through in the IIFE.

Also something I might include when I go back and edit.
