title: Can I create a WordPress plugin with JavaScript only?
body: <p>I am scared to ask this question, because StackOverflow is already warning me about my question being likely to be downvoted. But I am very curious about this.</p>
  
  <p>I have read that you must have at least one php file in your WordPress Plugin. Which sounds to me like you only need something like an index/entry php file.</p>
  
  <p>However, I wasn't able to find much about JavaScript in WordPress Plugins by using google. Which seemed weird to me, because we're talking here about the web of 2017.</p>
  
  <p>An answer would be very appreciated!</p>
