Benchmarking the loading time of app.ubervu.com, behind the scenes of the Loading Animation

gistfile1.js

function getTime() {
  return new Date().getTime() / 1000;
}
function seconds(time) {
  return time.toFixed(2) + 's';
}
// Start counting as soon as the website loads
var startedLoadingAt = getTime();
var loadingTime = 0;
var timerInterval = setInterval(function() {
  loadingTime = getTime() - startedLoadingAt;
  // Clear console before showing new time to only show current time
  console.clear();
  console.log('Loading ubervu for ' + seconds(loadingTime));
  // Since there's no easy hook for when the loading animation is rendered just
  // set its overlay with every iteration
  if (jQuery)
      $('#loading-animation').css('opacity', 0.5);
      // Same thing for catching when the loading animation is removed, check
      // every time
      if (!$('#loading-animation').is(':visible')) {
        console.clear();
        console.log('Finished loading ubervu in ' + seconds(loadingTime));
        // Stop interval, that's it
        clearInterval(timerInterval);
