<p><strong>Note</strong>: Do <em>not</em> use <code class="language-javascript">loadLanguages()</code> with Webpack or another bundler, as this will cause Webpack to include all languages and plugins. Use the babel plugin described above.</p>

<p><strong>Note</strong>: <code class="language-javascript">loadLanguages()</code> will ignore unknown languages and log warning messages to the console. You can prevent the warnings by setting <code class="language-javascript">loadLanguages.silent = true</code>.</p>
