Avoid serving legacy JavaScript to modern browsers

  • Hi, I installed the Kadence theme on my fresh WordPress install. Then when I checked the default “Hello world!” post using PageSpeed Insights, it gave me a warning saying “Avoid serving legacy JavaScript to modern browsers” on the mobile tab.

    The warning included the following files:
    tiny-slider.min.js?ver=1.0.5
    tiny-slider.min.js?ver=1.0.5:1:3338

    Is this something you can fix?

  • Hey,
    Thanks for posting, I’ll remove that polyfil for object keys in the next version. That will remove this from showing in the pagespeed insights and it will have a tiny sentence of code ??
