Check if an input field has focus in vanilla JavaScript

Question

Using jQuery, I can test if an input field has focus like so:

if ($("...").is(":focus")) {
    ...
}

How do I do that without using jQuery?

Taken from the above answer:

this === document.activeElement // where 'this' is a dom object

Example of use: if (document.activeElement.tagName === "INPUT") console.log("An input is focused");
