Angular 2 then has to remove the DOM and recreate all of the items for the purposes of animation. So the Angular perf test is doing a lot more then it should.\n\nThere are two ways to fix it:\n1. change `gerenerateGrid` to return an array with same identities.\n1. change `*ngFor` (https://github.com/bennadel/JavaScript-Demos/blob/master/demos/render-large-datasets-angular2-reactjs/angular.htm#L88) to use `trackBy` See: https://github.com/angular/angular/blob/master/modules/angular2/src/common/directives/ng_for.ts#L86 (It will be in beta4)\n\nTho above should make Angular significantly faster.\n\nMore reading: https://github.com/mathieuancelin/js-repaint-perfs/issues/19\n","author":{"url":"https://github.com/mhevery","@type":"Person","name":"mhevery"},"datePublished":"2016-02-10T01:29:12.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":6},"url":"https://github.com/3/JavaScript-Demos/issues/3"}
