[Contact Form 7] How to set Recaptcha.js so that it does not load on anything other than the contact page.
I am creating a contact form using Contact Form 7. I use Recaptcha to prevent spam, but because of this, Recaptcha.js always comes up in Pagespeed Insights in “Eliminate render-blocking resources” or in “Reduce unused JavaScript”. Therefore, I researched and implemented a method to prevent Recaptcha.js from loading on pages other than the contact page. Try putting the following code in functions.php.
```
function block_recaptcha_badge() {
 if ( !is_page( array( 'contact-me' ) ) ) {
 wp_dequeue_script( 'google-recaptcha' );
 wp_deregister_script( 'google-recaptcha' );
 add_filter( 'wpcf7_load_js', '__return_false' );
 add_filter( 'wpcf7_load_css', '__return_false' );
 }
}
add_action( 'wp_print_scripts', 'block_recaptcha_badge' );
```
If you have multiple contact form pages, you can increase the array(‘contact-me’ part, like below.
array( ‘contact-me’, ‘contact-me’, ‘contact-me-3’

How to load WordPress JavaScript asynchronously
By putting the following code in functions.php, you can load WordPress JS asynchronously. Effective if jquery.js or jquery-migrate.min.js appears in “Exclude resources that prevent rendering” in PageSpeed Insights.
```
if ( !(is_admin() ) ) {
    function replace_scripttag ( $tag ) {
        if ( !preg_match( '/\b(defer|async)\b/', $tag ) ) {
            return str_replace( "type='text/javascript'", 'async', $tag );
        }
        return $tag;
    }
    add_filter( 'script_loader_tag', 'replace_scripttag' );
}
```
However, if I do this, my PageSpeed Insights score will go up, but the Cocoon blog card image won’t display properly, so I changed it back.
