title: javascript ArrayBuffer, what's it for?
body: <p>Maybe it's late, or maybe it's the sake, but I just read the docs for <a href="https://developer.mozilla.org/en/JavaScript_typed_arrays/ArrayBuffer" rel="noreferrer">ArrayBuffer</a> and can't think of a single thing it would be really useful for.</p>
  
  <p>Can someone enlighten me?</p>
  
  <p>Are there any uses anyone can think of that don't involve images?</p>
