title: Simplest way to obfuscate and deobfuscate a string in JavaScript
body: <p>I'm looking for a way to obfuscate and deobfuscate a string in JavaScript; by which I mean encryption and decryption when security is not an issue. Ideally something native to JS (like <code>base64_encode()</code> and <code>base64_decode()</code> in PHP) to "turn a string into something else and back again" without having to write a function.</p>
  
  <p>Any suggestions welcome!</p>
