Bunch of useful filters for angularJS(with no external dependencies!)

/**

angular.module('a8m.where', [])
  .filter('where', function() {
    return function (collection, object) {
      if(isUndefined(object)) return collection;
      collection = isObject(collection)
        ? toArray(collection)
        : collection;

      return collection.filter(function (elm) {
