Why does alert appear before background changes?

Question

So, I\'ve been trying stuff lately and got this piece of code in my script:

document.body.bgColor = \"red\";
alert(\"hello\");

But in Chrom

Answer 1

The simplest workaround will be like:

document.body.bgColor = "red";
setTimeout(function() {
        window.alert('Hello There!');
    },  10);

The timeout value "9" is the minimum in my case, if i use <9, alert appears first.
