title: Get current language next-i18next
body: <p>I am using NextJS with next-i18next. This is my home page:</p>
  
  <pre><code>import {withTranslation}  from '../config/next-i18next';
  
  const Home = function Home() {
    return (&lt;div&gt;test&lt;/div&gt;)
  };
  
  Home.getInitialProps = async () =&gt; {
    return {namespacesRequired: ['home']}
  };
  
  export default withTranslation('home')(Home);
  </code></pre>
  
  <p>What I want is to get current language inside a component/page, how can I do that ?</p>
