Simulate long script on page load

Question

I am trying to simulate a script that takes a long time to run on page load.

I tried this:

window.onload = function() {
  setTimeout(alert("Page Rendered"), 200000);
};

But alert message happens instantly.

What am I doing wrong?

Check the function(). docs

window.onload = function() {
  setTimeout(function(){alert("Page Rendered")}, 200000);
};
