As far as I know document.getElementById('myId') will only look for HTML elements that are already in the document. Let's say I've created a new element via JS, but that I haven't appended it yet to the document body, is there's a way I can access this element by its id like I would normally do with getElementById?As far as I know document.getElementById('myId'
