Javascript: check for ::after in element

I have a very simple element:
enter image description here
How can I check if this element contains the ::after using Javascript?

(I have the element using document.getElementsByTagName('h2')[0])

I don't know how the thing works, and I don't need to know, I just need the code to see if it exists...

In some cases the element looks like this:
enter image description here
I need to be able to detect both cases, if possible!
