Quick and dirty methods for object cloning and comparison using the JSON parser

utilities.js

// Create a copy of x without reference back to x
function clone(x){
  return JSON.parse(JSON.stringify(x));
}

// Pass any number of arguments of non-function type. Returns true if they are all identical.
function areEqual(){
  for(var i = 1, l = arguments.length, x = JSON.stringify(arguments[0]); i < arguments.length; ++i){
    if(x !== JSON.stringify(arguments[i])){
      return false;
    }
  }

  return true;
}
