Window resize event listener with an added delay. This stops the resize event from firing constantly while resizing. Basically a debounce for scrolling

window-resize-delayed.js

function someNamedFunction() {
  // fires 200 ms after the last scroll event  
}

function handleResize() {
  clearTimeout(this.delayer);
  this.delayer = setTimeout(someNamedFunction, 200);
}

window.addEventListener('resize', handleResize);
