title: Reading from & writing to files in same domain using JavaScript
body: <p>Say I have a website hosted via Bluehost or the like, at <code>example.com</code>. If I have a file stored at <code>example.com/a.txt</code>, how can I go about reading from this file? And, if I want to write a new string to this file, is it possible to do so, or is it impossible with JavaScript in the web?</p>
