How Angular works | Kara Erickson |

Angular is many things to many people, but at its heart, it's a set of tools to render content, organize applications, and manage data. Find out about how Angular works under the hood and get insights into the challenges we faced and the decisions we've made by learning how everyday Angular features from change detection to queries actually work.

This was a really great talk. I've never heard any of the details of Angular's runtime behaviour explained so well. Only negative is I wish it had been longer! I would have really liked if it had carried on to talk about the more tricky bits like embedded views. Nevertheless, excellent stuff.

[@AkkayHT228]

Great talk! I’m already have pure understanding about more of these concepts

Is there error at 11:28 , mentioning of component as an directive only.

[@Ratchet2022]

In Angular, Components are a subset of Directives. So the InfoCard and Footer Components are also Directives.

at the end of the presentation, she is showing lifecycle hooks and mentioning: " some of them are node by node and some view by view in run time ". I don't understand how this information can help me to increase the performance of my app ? how this information can help me or is any case we should consider for designing with knowing this fact?

[@dependencyinjection2966]

Does she promises you that the information she provided must help you? Not satisfied? Walk by ;)

26:53 invoking lifecycles on img+h1 tags :/ ... I dont understand, lifecycles only make sense on Angular Decorated classes ...

[@tengyunwang3976]

The part talking about hooks is quite fast and confusing.

[@peppigue]

Angular is a great example of what a mess navigating tech documentation and tutorials is. I don't like the official ng intros as they don't explain why things are done the way they are. This leads me to vids like this, where the explanations are slightly too techie. It's easier to learn something like embedded systems, which to most people seems advanced. I guess it's because it's close to the metal. When software is built on software built on software - that's where the complexity of understanding what goes on under the hood comes from...

[@omarkarim9298]

Kind of a pointless argument to be comparing an abstraction framework like angular to embedded systems lol

[@GrantParks]

Frameworks are a contrived complexification that continue to degrade the WWW.

[@ZtowhyA]

she's pretty... ;)

[@sergey13]

Thanks God gave us React instead of this nightmare.

[@crapmailtome5621]

I did not get why Angular is needed in the first place. What's the history? What was the need of this? Were the existing technologies failing at something?

[@amosisaila8416]

You don't know why? I want to watch you implementing your own Compiler :)

[@pmoney8701]

I need to find me a wife as beautiful and techie as her❤️
