title: How to detect if browser supports file uploading? (Mobile + Desktop)
body: <p>I'm developing an application for both mobile and desktop browsers. I'm wondering if there is anyway to detect if a browser supports file uploading. I'm looking specifically for feature detection and not browser detection. Is there any way to find out?</p>
  
  <p>Server-side or client side is fine.</p>
  
  <p>Thanks</p>
