如何在AngularJs中剪断细绳

var app = angular.module('myApp', []);

    app.controller('myCtrl', function ($scope) {
        $scope.phrases = ["Shiloh Match Jolie", "Zahara Marley Novel", "Pax Dix Bat", "Maddox Chivan Jcalie"];
     
        // Returns the last word of a phrase
        $scope.getLastWord = function (phrase) {
            var words = phrase.trim().split(' ');
            return words[words.length - 1];
        };
        
        // Returns the last character of a phrase
        $scope.getLastCharacter = function (phrase) {
            // Assuming the phrase is not empty
            return phrase.trim().slice(-1);
        };
    });

<div ng-app="myApp" ng-controller="myCtrl">
    <ul>
        <li ng-repeat="phrase in phrases">
              Last Word in the Pharse : {{ getLastWord(phrase) }}
              Last Character in the Last Word of the Pharse: {{ getLastCharacter(phrase) }},
        </li>
    </ul>
</div>
