title: JavaScript Endian Encoding?
body: <p><a href="https://stackoverflow.com/questions/503052/javascript-is-ip-in-one-of-these-subnets/503238#503238">A response on SO</a> got me thinking, does JavaScript guarantee a certain endian encoding across OSs and browsers?</p>
  
  <p>Or put another way are bitwise shifts on integers "safe" in JavaScript?</p>
