Faster Angular Applications – Part 1. On Push Change Detection and Immutability

On AngularConnect 2017 in London I gave a talk called “Purely Fast”. In the presentation I shown how step by step we can improve the performance of a business application. In the example I incorporated as many performance issues as possible which I faced over the past a couple of years developing enterprise Angular and AngularJS applications. After the presentation I got great feedback for the content so I decided to write a series of blog posts which aim to explain the content from “Purely Fast” in details.
