IE supports forEach(…) when invoked fromthe console but not when called from the code

Question

I\'m running this snippet the console. In IE it produces the output just as expected. Running the same in Cr and FF for reference confirms the congruence of behavior.

Little late, but it might be useful if someone has the same problem and doesn't want/can't replace all forEach methods with [].forEach.call(elements, fn(el)). Here is polyfill that works for ie11

if (! Object.getOwnPropertyDescriptor(NodeList.prototype, 'forEach')) {
    Object.defineProperty(NodeList.prototype, 'forEach', Object.getOwnPropertyDescriptor(Array.prototype, 'forEach'));
}
