jQuery Migrate dramatically simplifies the process of moving older jQuery code to a higher jQuery version by identifying deprecated features. It then restores deprecated features and behaviors so that older code runs properly on the current jQuery version and later.
Most up-to-date frontend code and plugins don’t require jquery-migrate.min.js. In most cases, this adds unnecessary load to your site. You can see this running if you launch the Chrome Devtools console.
Other reasons to remove jQuery Migrate:
- It’s better to keep your code, themes, and plugins updated than to patch them in support of an extra file. Keeping your site updated also prevents it from Security attacks.
- If you are running plugins that use older jQuery code, it’s probably better to update them or switch to an alternative that keeps them updated.
How to remove jQuery migrate from WordPress?
Removing jQuery migrate from WordPress is relatively easy. You need to add the following lines of code to your theme’s functions.php file.
//Remove JQuery migrate
function remove_jquery_migrate( $scripts ) {
if ( ! is_admin() && isset( $scripts->registered['jquery'] ) ) {
$script = $scripts->registered['jquery'];
if ( $script->deps ) {
// Check whether the script has any dependencies
$script->deps = array_diff( $script->deps, array( 'jquery-migrate' ) );
}
}
}
add_action( 'wp_default_scripts', 'remove_jquery_migrate' );Another straightforward way to disable it is by adding Remove jQuery Migrate plugins.

Helllo Amit,
Is it OK to add the above code in NewsPaper theme? Will it improve the performance?
Hi Giri,
Yes, you can add the mentioned code in the Newspaper theme. jQuery Migrate script will be removed by default from WordPress 5.7 (Upcoming update).
I hope you will find this helpful.
Never mind! I’ve created this and it works 🙂
function remove_jquery_migrate_in_admin() {
global $wp_scripts;
$wp_scripts->remove(‘jquery’); // Remove default (because of jQuery Migrate dependency).
$wp_scripts->remove(‘jquery-migrate’); // Prevent jQuery Migrate from being enqueued.
$wp_scripts->add(‘jquery’, false, array(‘jquery-core’), ‘1.2.1’); // Add jQuery without jQuery Migrate.
}
add_action(‘admin_enqueue_scripts’, ‘remove_jquery_migrate_in_admin’);
