> The script attempted to modify a div's background color using document.body.removeChild, but as the script was loaded in the HTML head, the DOM had not loaded yet and document.body was not available, causing the script error. Don't we have computers to catch such faults?

Isn't it best practice to wait for document.loaded before starting JavaScript shenanigans?

  I thought so, but the bigger problem here is not failure to wait but failure to verify safety.

    Ok, now I got what you meant. I was completely amiss.

Well, that's web engineering basics 101: HTML/CSS/JS should be treated as sequential (line-by-line processed). Therefore, even linkting to JS before any HTML tag will result in no element being in the DOM (while the JS is called).

  Indeed. Simple enough for a computer to check. So was Google short of computers? ;)

    Apparently. We should open gofundme for Google.
