<p>In some critical cases you cannot wait for a JavaScript file to load. Then you can benefit from better performance, if you embed the JavaScript code directly into the <code><script></code> tag. This is where this plugin comes in: It provides a filter <code>embed_javascript_file_content_handles</code>, which takes JavaScript handles and echos their code content into the DOM instead of linking to a file.</p>
<p>Please beware that placing lots of embedded JavaScript code can be critical! First you lose caching benefits and second the document size can increase easily. A general rule of thumb is that you should only consider JavaScript files for inline placement, which are critical and which have a file size lower than ~500 Bytes.</p>
<h4>Example</h4>
<pre><code>add_action( 'wp_enqueue_scripts', 'my_scripts' );
function my_scripts() {
    // Some critical script is enqueued
    wp_enqueue_script( 'js-detection', get_template_directory_uri() . '/js/js-detection.js' );
}

/**
 * Define JavaScript handles to be echoed inline in the html head section.
 */
add_filter( 'embed_javascript_file_content_handles', 'my_embed_javascript_file_content_handles' );
function my_embed_javascript_file_content_handles( $handles ) {
    $scripts = [ 'js-detection' ];

    return array_merge( $handles, $scripts );
}
</code></pre>
