If you change the window.history.pushState() call to window.history.replaceState(), it doesn't add bazillions of entries to your history, which makes it slightly more practical. javascript:var dashes = ""; var num = 20; while(--num) dashes += "-"; setInterval(function() { window.history.replaceState("", "", dashes.slice(0, num % 20) + "foo" + dashes.slice(num % 20)); num++;}, 500)
