Variables declared with `var` are also accible after accessing the
scope. This lead to shadowing because variables with the same name are
declared in a later scope.
Ref: #7812
Since variables declared with `var` don't respect all scopes, when used
in a loop it doesn't create a new variable each iteration. The
initializer value is always assigned to the same variable. That makes
problems when the variable is used in a callback. To work around that
the variable is copied in to a IIFE.
When not using `var` the iife isn't required.
Ref: #7812
This fixes all issues eslint can safely do automatically. Drastically
reducing the number of open style issues reported.
