Render-blocking JavaScript

  • Hi all,

    in page speed otimization for mobile the major issues are related to render-blocking JavaScript for this plugin js e.g.

    /wp-content/plugins/contact-form-7-datepicker/js/jquery-ui-sliderAccess.js
    /wp-content/plugins/cotact-form-7-datepicker/js/jquery-ui-timepicker.js

    In which file is necessary to add the “async” statement ?

    Thanks,
    nerimizi
