No, it's an HTMLCollection, not an Array.

It has Array-like characteristics, like numeric properties, and a .length property, but it does not inherit from Array.prototype. Therefore it does not have the standard Array methods, and so should be seen as being different.

Another significant difference is that HTMLCollection is a "live" collection, which means that it updates as the DOM updates. If you remove one of its nodes from the DOM, it will be removed from the HTMLCollection automatically.
