Remove jQuery Migrate Safely
·
Completely removes the jQuery migrate script dependency safely from your WordPress website thereby improving page load speed on the frontend.
jQuery Migrate is a javascript library that allows you to preserve the compatibility of your jQuery code developed for versions of jQuery older than 1.9. It basically restores deprecated features and behaviors so that older code will still run properly on the current jQuery version and later.
Most websites that use up-to-date themes and plugins don't require jQuery Migrate on the frontend, and thus the script can be safely removed. By removing it, the browser will have one less JavaScript file to download and execute. As a result, your site will load faster!
