More optimizations techniques: runOutsideAngular heavy scripts or 3rd party libraries, detach view from change detection, lazy-load components via dynamic imports, avoid many *ngIfs, ngSwitches in templates and use dynamic components, virtual scroll for large lists, server-side pagination, caching, service-workers.

Greetings from Kyiv :)
Spent my last week searching new job as Front-End Developer with Angular. Can strongly confirm that all questions you mentioned - I heard them myself. DI and CD are really primary patterns in Angular and developer should know its native implementations.
ps. btw, most of advanced topics I was asked during tech-interview are covered here, explained by Dmytro. Got 5+ job offers eventually.

You'll never escape without "Different type of subjects" :)), but yes, your points of view are very real.

Hello Dmytro !!
Best wishes from India, I love to watch your videos - the content is un-paralleled. In this video on the optimization topic - I think we should also mention the output compression e.x. gz compression, brotli compression from web server end which also decreases the bundled js files. Just a thought. Thanks again and keep making these wonderful videos.

change detection, page load, UX improvements, Server-side rendering with Angular Universal, Lazy load routes, Optimizing bundling and preloading
, Cache HTTP calls and Cache static content using Angular PWA, Using trackBy in ngFor
. The way you should go about any improvement in a system is that you should first identify bottlenecks

[marekkazimierczak]

All right! So I'll mention your YT channel, as a good source of Angular news on my following job interview 😄
