Do you also worry that if you wrote:
x = 0;
setTimeout(function() { x = 1; }, 0);
console.log(x);
console.log(x);
console.log(x);
console.log(x);
console.log(x);
console.log(x);
that there's a risk that you'd get a few 0's in the log, but at some
point it would switch to logging 1's?
No developer that I've talked to think that that could happen in JS.
And it can't. It's clear to everyone that you'll only get 0's. The
reason is that JS is single threaded and the setTimeout callback is
run asynchronously.
It's the same thing in IDB. The .onsuccess property is triggered
asynchronously which means that it couldn't happen in the middle of
your execution.
