Generate a Hash from string in Javascript

Question

I need to convert strings to some form of hash. Is this possible in JavaScript?

I\'m not utilizing a server-side language so I can\'t do it that way.

Answer 1

A fast and concise one which was adapted from here:

String.prototype.hashCode = function() {
  var hash = 5381, i = this.length
  while(i)
    hash = (hash * 33) ^ this.charCodeAt(--i)
  return hash >>> 0;
}
