## Description

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 `<script>` tag. This is where this plugin comes in: It provides a filter `embed_javascript_file_content_handles`,
which takes JavaScript handles and echos their code content into the DOM instead
of linking to a file.

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.

#### Example

    ```
    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 );
    }
    ```
