Global scope pollution

[dfsq]

There are several places where variable definitions lick into global scope. For example:

for( ix in sections ) { ... }

In the above example ix variable should be declared with var keyboard, otherwise ix becomes global variable.

*leak

This is lick ;)

I think the IIFE protects from global leakage into the other scripts? But perhaps a few extra var inside sub-functions can help with garbage collection...

Lick :)

No, even though wrapped into IIFE, assignment to undeclared variable will result into global variable. More over in strict mode there would be "ReferenceError: assignment to undeclared variable" error.
