Check if is an Object
<p>I need to check if a variable is a pure Object instance. For example: a HTMLElement is <em>instanceof</em> Object. But I really need to check if it is <em>only</em> an Object, like <code>{a: true, b: false}</code> is. It not can validate an Array.</p>

<p><em><strong>Note</strong>: I can use newer features of Chrome, if better.</em></p>
