Answer 1

DOM4 now defines NodeList as an iterable:

iterable;

According to the IDL draft, that means

An interface can be declared to be iterable by using an iterable declaration (matching Iterable) in the body of the interface.

iterable;
iterable;

Objects implementing an interface that is declared to be iterable support being iterated over to obtain a sequence of values.

Note: In the ECMAScript language binding, an interface that is iterable will have “entries”, “forEach”, “keys”, “values” and @@iterator properties on its interface prototype object.

If a single type parameter is given, then the interface has a value iterator and provides values of the specified type.
