i got disappointed angular... i'm trying quite simple presentation-layer stuff , can see no solution while browsing web (and stack overflow well). the case is: i've got list of elements generate links to, of them comma-separated in html . let's it's: var list = [{id: 1, name: "ab"},{id:2, name: "cd"}, ...]; my link should like: <a href="#/somelink/{{ el.id }}">{{ el.name }}</a> easy, isn't it? so, basing on other questions, tried this: <a ng-repeat="el in list" href="#/somelink/{{ el.id }}">{{ el.name }}</a>{{$last ? '' : ', '}} which doesn't work, because ng-repeat inside ng-repeat , $index , $last , $first caught outer ng-repeat values instead of inner one, want. moreover, don't making html one-liner 5 things @ time, because [1] costs read , [2] it's easier mess something, while changing, because of complexity. prefer split more lines. but ...

creating 2 constructs university second semester computer science count words in text. 1 implementation uses array word-objects save word string , frequency int. other uses hashmap word key , frequency value. function "totalwords" should return sum of frequency. in hashmap variant: return _map.values().stream().reduce(0, (a, b) -> + b); in array variant: return arrays.stream(_words) .map((word) -> word != null ? word.count() : 0) .reduce(0, (a, b) -> + b); my problem is: in junit test short test text array variant need approximately 0.001s , map variant needs 0.040s , not understand why map need more time. has explanation , maybe better solution? one of reason iterating hashmap can slower array , reason locality . computation bottleneck of modern processor dominated memory access, , that's why cache used. array stores data in contiguous chunk of memory, means when swap chunk of memory cache, more using in cache, o...
