tagName property

The tagName property contains the tag name in upper case (in capital letters).

Syntax

element.tagName;

Let's obtain the #elem element and output its tag name:

<div id="elem"></div>

let elem = document.getElementById('elem');
console.log(elem.tagName);

The code execution result:

'DIV'

Let's output a tag name in lower case. To do this, use the toLowerCase method:

<div id="elem"></div>

let elem = document.getElementById('elem');
console.log(elem.tagName.toLowerCase());

The code execution result:

'div'
