However, here in this video you mentioned opposite.

[@user-lm3pm4mb3m]

here we have used super keyword in parent component js as well and according to syntax we need to pass some argument in super method which constructor are we caliing inside parent constructor exactly? I am a bit confused about exact use of super method

[@SalesforceHulk]

Use of super keyword varies from Lang to Lang, in js, you need to call super method in a child class as we are extending the parent class(LightningElement).
If there's any confusion, We recommend exploring the oops basics in js, which should provide clarity.

[@anjumtadmod8956]

if the parent component is rendered again when you were explaining about the disconnected callback. Then why the contructor and connected callback of parent is not called ?

[@SalesforceHulk]

The reason is that constructor and connected callback only get called when the whole component gets connected to the UI

[@preetibharti2803]

Nice 👍

[@SalesforceHulk]

Thanks ✌

[@vedantilasnapure9939]

As you said if error happens loading child , errorcallback will fire
My ques what is what if there is error load parent component then ?
Pls let me knw

[@SalesforceHulk]

Simple!
Then parent component will stuck, loading will not get completed.

[@anubhavsingh8144]

@@SalesforceHulk for child if error happens it's taken care by errorcallback() on parent but if error happens on parent, how it will be well handled ?

[@riteshtiwari1446]
