From jQuery to JavaScript and back again

Iterating a NodeList isn't so bad:

  Array.prototype.forEach.call(
  document.querySelectorAll('a'), function(el){ 
    console.log(el); 
  });

But, I agree with the point. If the NodeList isn't live, like it is for the other DOM querying methods, then what is the point in returning a NodeList instead of an array?

The DOM WebIDL does not know what an array is. Though an IDL extension/annotation added some time ago allows inheriting IDL interfaces from core language objects or interfaces rather than the root object (http://dev.w3.org/2006/webapi/WebIDL/#ArrayClass), and DOM4 adds this annotation to NodeList http://dom.spec.whatwg.org/#interface-nodelist

FWIW, they fixed that crap in Dart. All those array-like things are indeed just regular arrays.
