[JS] Losing work / edits due to crashes? [TIP]

Question

SL can spontaneously reset* if you leave rogue timers. You should clear them ALL when visitors leave:

function frame(timestamp) {
...
}

var myTO = setTimeout(frame, 17);
var myIV = setInterval(frame, 17);
var myAF = requestAnimationFrame(frame);

// Fires when leaving [Output]
window.onbeforeunload = function() {
clearTimeout(myTO);
clearInterval(myIV);
cancelAnimationFrame(myAF);
}

* A completely sane response.
