/**
 * Loads a script from a specific URL. React Native cannot load a JS
 * file/resource/URL via a <script> HTML element, so the implementation
 * fetches the specified <tt>url</tt> as plain text using {@link fetch()} and
 * then evaluates the fetched string as JavaScript code (using {@link eval()}).
 *
 * @param {string} url - The absolute URL from which the script is to be
 * (down)loaded.
 * @returns {void}
