AngularJS 1.8: Difficulty with custom filter and binding to input field updates
I'm building a feature where I'm confused about I am currently working with AngularJS 1.8 and working with an scenario with a custom filter that I created for a list of objects. The filter is supposed to update the displayed list based on the user's input in a text field, but I am experiencing a delay in the updates where the filter does not reflect the changes immediately. Here’s a simplified version of my setup: ```javascript angular.module('myApp', []) .controller('MainCtrl', function($scope) { $scope.items = [ { name: 'Apple' }, { name: 'Banana' }, { name: 'Cherry' }, { name: 'Date' } ]; $scope.searchTerm = ''; }) .filter('customFilter', function() { return function(items, searchTerm) { if (!searchTerm) return items; return items.filter(item => item.name.toLowerCase().includes(searchTerm.toLowerCase())); }; }); ``` In the HTML, I use this filter like so: ```html <div ng-app="myApp" ng-controller="MainCtrl"> <input type="text" ng-model="searchTerm" placeholder="Search items..." /> <ul> <li ng-repeat="item in items | customFilter:searchTerm">{{ item.name }}</li> </ul> </div> ``` Despite setting everything up, I notice that the list is not updating instantly as I type. There is a noticeable delay, which makes it feel non-responsive. I've also tried using the `ng-change` directive to manually trigger a digest cycle, but that hasn't seemed to resolve the scenario. The console shows no errors, which is puzzling me. Could this behavior be related to Angular's two-way data binding, or is it a performance scenario with the filtering of a list? How can I ensure that the list updates in real-time without delays? Any insights or suggestions would be appreciated. What's the correct way to implement this? I'm working on a mobile app that needs to handle this. Any ideas what could be causing this?
