Debouncing the window resize event

Just a quick tip if you want to run some code on window resize but want to avoid freezing / slowing down the user's browser. The code below will run doSomething after the user is "done" resizing the window (in this case 500ms after the last resize event).

  window.resizeTimeout = window.setTimeout(() => {
  }, 500)
