Answer 1

It's because you defined the variabld before the page loaded, therefore it will be null.

window.onload = () => {
document.getElementById(1) = "oma";
}

Also note that using numbers for ids is a bad practice

Answer 7

I guess I wasn't really paying attention. I just meant that you tried to get an element which didn't exist yet

Answer 8

How it didnot exist yet?!
I wrote it in html body ??

Answer 9

No, it just means it didn't exist at the time you ran the function, because the page wasn't loaded.That's why you should use the window.onload function, which will only run when the document is loaded
