Well...he wasn't satisfied...wanted to see it in JavaScript...sigh

dollarz.js

var DANNY_ALIASES = ['Danny', 'D$', 'Dollarz', 'D Dollarz'];

// hwa? why isn't he using underscore or loadash? #STFUUUUUUU!!!!!
DANNY_ALIASES.include = function(item) {
  var include = false;

  for(var i = 0; i < this.length; i++) {
    if (this[i] == item) {
      include = true;
      break;
    }
  }

  return include;
};

// hwa? why doesn't he just use extend and mixin the functionality? #STFUUUUUUU!!!
// the answer to both your questions is because he DOESN'T WANT TO!!!
// LET'S ALL BE DIFFERENT...ON PURPOSE.......NOW!!!!!!
DANNY_ALIASES.forEach(function(item) {
  item.eql = function(other) {
    return DANNY_ALIASES.include(other) && DANNY_ALIASES.include(this);
  };
});

for(var i = 0; i < DANNY_ALIASES.length; i++) {
  var item = DANNY_ALIASES[i];
  var nextItem = DANNY_ALIASES[i + 1];

  if (nextItem) console.log('%s == %s', item, nextItem);
}
