Question

I want to add a keydown event listener to the document object without JQuery.

In the listener I’m not accessing the DOM. The only thing I need from the DOM is the document object itself. I only want to disable pressing of certain key.

Is it safe to call it directly in the script (I mean when the script loads), or do I need to use onload callback (or maybe something else)?

Thanks in advance.

The document object is always available wherever you place your script. No need to wait for DOMContentLoaded or anything; just add your listener whenever you like.

This is not true for elements within the document.
