title: Is there a polyfill for window.performance.getEntriesByType in Safari?
body: <p>Looks like <code>window.performance.getEntries</code> and <code>window.performance.getEntriesByType</code> are not defined in Safari.</p>
  
  <p>Is there a polyfill for those functions? Or did someone created sort of alternative?</p>
  
  <p>What I want to do is to get all resources loaded in the page. (all images, css and js files)</p>
