The blend of debounced resize event with orientationchange flavor. See the demo.

window.addEventListener('resize:end', function(event) {
  // Your callback, e.g.
  console.log(event.type);
}, false);

The resize:end (and resizeend) event is dispatched in two cases:

It’s the cure for those window.onresize skips that occur every pixel as long as you keep resizing your browser’s window. Details matter. performance++, too.

Switching from portrait mode into landscape (and vice versa) triggers resize:end. If rotating a device doesn’t alter its viewport dimensions (e.g. rotating it upside down), the event isn’t dispatched, because there’s simply no need to.

Tested in the following browsers:

• Safari 6+
• Chrome 20+
• Firefox 14+
• Opera 12+
• Internet Explorer 9+
• Mobile Safari on iOS 6+
