javascript get element’s tag

Lets say this is my HTML:

<div id="foo">
<input id="goo" value="text" />
<span id="boo">
</span>
</div>

I would like to be able to determine what tag belongs to a html element.

Example element with id “foo” = div, “goo” = input, “boo” = span

So something like this:

function getTag (id) {
   var element = document.getElementById(id);
   return element.tag;
}

Answer

HTMLElement.tagName

const element = document.getElementById('myImgElement');
console.log('Tag name: ' + element.tagName);
// Tag name: IMG
<img src="http://placekitten.com/200/200" id="myImgElement" alt="">

NOTE: It returns tags in capitals. E.g. <img /> will return IMG.
