Get the type of attribute on a Html element

Question

Let say that I want to find the types of attributes attached to a HTML element. To be clear, I don't want to list the attributes of an element, for each attribute I would like to find it's attribute type, and not it's value or name. eg. I have a div with several attributes, I want to print to the console the types of attributes that are attached to the element. in this case it should print an array with the value [event] <div onclick='someFunc()'>some text</div> getAttribuyteType() // event
