Hello, I think if u use the async pipe in html component you will be detect changes without using the changeDetectorRef and you will not use the ngdestroy life cycle hooks Because the async pipe do the unsbscription at the end of html rendering process

Hi sir, This is Ramya. Change Detection occurs in parent to child component or any other components which is not having any parent child communication ? This is my doubt

Could someone please explain to me why there are four consoles at the initial load? Shouldn't there be only two?

[@darnaryelfantaisie5737]

That's because the Angular change detection cycle (the process by which Angular compares the component tree with its own internal view of said tree, to detect if there was any change) is done twice in DEV mode (not in PROD). This check is done by reference (like for all objects and array in javascript), which is also why the data doesn't show in the video: when he does 3:00 "this.posts = data", the reference to "this.posts" is not changed. He's simply making the "posts" variable point to the object "data", containing the data, which is why the internal data is clearly changed as seen in the console. To make sure Angular picks up the change, it's only necessary to make sure the reference to "this.posts" is changed, for example by using the spread operator and doing something like "this.posts = {...data}". I think it is well explained here : kzbin.info/www/bejne/Y6WlXoR6p7Wgq6ssi=WgfOOnGqaoFU5AcP&t=149
