Disable jQuery Migrate

README.md

I drop this in WPMU_PLUGIN_DIR when developing.

WPMU_PLUGIN_DIR defaults to wp-content/mu-plugins/ but is configurable in wp-config.php

no-jquery-migrate.php

<?php

add_filter( 'wp_default_scripts', function ( &$scripts ) {
    if( ! is_admin() ) {
    	$jquery_version = $scripts->registered[ 'jquery' ]->ver;
        $scripts->remove( 'jquery');
        $scripts->add( 'jquery', false, array( 'jquery-core' ), $jquery_version );
    }
});
