Installation

add_action( 'wp_enqueue_scripts', function () {
	wp_enqueue_script( 'recaptcha', 'https://www.google.com/recaptcha/api.js' );
	wp_scripts()->add_data( 'recaptcha', 'async', true );
} );

How to defer loading of a script:

<?php

add_action( 'wp_enqueue_scripts', function () {
	wp_enqueue_script( 'recaptcha', 'https://www.google.com/recaptcha/api.js' );
	wp_scripts()->add_data( 'recaptcha', 'defer', true );
