It sounds like you're wondering if

window.addEventListener("load", function() {
  document.body.innerHTML = "foo";
}, false);

is the same as:

document.body.innerHTML = "foo";

They are almost the same. The second one will happen a little sooner,
and so there won't be as much flicker (still some, particularly if you
replace the entire document's HTML, as you are). Also, the second one
sometimes crashes the browser, only on some pages. You will have to
test it and see if it does in your case.

No, sorry.

Right.
