Please, avoid jQuery

Please refrain from assuming that jQuery is in use, especially when there isn’t much reason for it. For instance, the JS in the file “includes/class-ctn-load-time.php” on line 80, instead of the code:

//ctn loadtime display
(function($) {
    $(document).on('ready', function () {
        $('.ctn_load_time_in_sec').text(<?php echo $this->load_time; ?> + " seconds");
    });
})(jQuery)

It’s better to use vanilla js, which is also more elegant:

//ctn loadtime display
document.addEventListener('DOMContentLoaded', () => {
    let o = document.querySelector('.ctn_load_time_in_sec');
    o && (o.textContent = <?= $this->load_time ?? 'unknown' ?> seconds);
});

In any case, thank you for the plugin.
