javascript angularjs json

Javascript 根据angularjs中的键和最新时间戳键过滤json,javascript,angularjs,json,Javascript,Angularjs,Json,我有一个JSON文件，它是从远程api获取的，包含不同的应用程序名称、时间戳以及其他细节。我需要用两个过滤器过滤这个json，即App name+latest timestamp。json文件如下所示： { "data": [ { "appDetails": [ { "appDescription": [ { "appName": "

请帮助我，因为我对javascript和js都是新手。如果能根据appName键和最新时间戳在angularjs代码中过滤数组，我将不胜感激。提前谢谢

使用

按名称分组，内部有一个测试来比较时间戳：
