How to disable script loading for mobile devices?

Question

JavaScript

I want to disable the loading of the Yandex.maps script on mobile devices, because the map does not appear on them. I tried to write in the HTML file like this:

<script type="text/javascript">
    if (document.body.clientWidth > 640) {
      document.write ('<script src="https://api-maps.yandex.ru/2.1/?apikey=[тут мой API key]&lang=ru_RU" type="text/javascript"></sc' + 'ript>');
    }
  </script>

Gives 2 warnings and an error:
