Angular Factory Boilerplate

angular-factory.js

(function() {
  'use strict';

  angular
    .module('', [])
    .factory('serviceName', serviceName);

  serviceName.$inject = [];

  function serviceName() {
    let factory = {
      square: square
    };
    
    function square(n) {
      return n * n;
    }

    return factory;
  }
})();

@vjwilson good I'll make these changes.
