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

/**
 * @ngdoc filter
 * @name ucfirst
 * @kind function
 *
 * @description
 * ucfirst
 */
angular.module('a8m.ucfirst', [])
  .filter({
    ucfirst: ucfirstFilter,
    titleize: ucfirstFilter
  });

function ucfirstFilter() {
  return function (input) {
    return isString(input)
      ? input
      .split(' ')
      .map(function (ch) {
        return ch.charAt(0).toUpperCase() + ch.substring(1);
      })
      .join(' ')
      : input;
  }
}
