This book is an insightful journey through the most valuable design patterns, and it will provide clear guidance on how to use them effectively in Angular. You will explore some of the best ways to work with Angular and how to use it to meet the stability and performance required in today's web development world. You’ll get to know some Angular best practices to improve your productivity and the code base of your application. We will take you on a journey through Angular designs for the real world, using a combination of case studies, design patterns to follow, and anti-patterns to avoid.

When these loops iterate over static collections, it sure takes time to process when the page is being generated, unless there is nothing you can do about it. You can still apply the patterns we saw earlier in this chapter to reduce your collection depth and to save on heavy calls made on a per-item basis. Where real performance problem arise, however, is when these loops are bound to a collection that evolves asynchronously. Indeed, Angular, and all frameworks allowing these kinds of bindings for that matter, repaint the collection every time it changes. Indeed, it can now show which items inside...
