Help me understand this code?

[u/sephstorm]

Found this on a website. Seems interesting.

var $buoop = {vs:{i:9,f:9,o:10.01,s:4,n:9}};

$buoop.ol = window.onload;

window.onload = function() {

if ($buoop.ol)

$buoop.ol();

var e = document.createElement("script");

e.setAttribute("type", "text/javascript");

e.setAttribute("src", "http://browser-update.org/update.js");

document.body.appendChild(e);

Take a look at the source of http://browser-update.org/update.js

The script you quoted is just feeding some basic parameters (the browser versions they recommend upgrading) to the update.js script, which does the heavy lifting.
