[yeswanthsairam]

Hi, Implementing the same code in LWC but only constructor method is returning but not connectedcallback and renderedCallback any specific reason for that?

[DevPalliSri]

Doubt :
In Parent Child Component Video (Previous video), you mentioned Child shouldn't be Exposed And No need to write Targets.
However, here in this video you mentioned opposite.
Could you please clear this doubt. Thank you.

[PratikMahajan-slmp]

Sir do you have any online lwc full course please mention

[YuvrajPawar-or]

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

[deeptiramlingappa]

Thank you for explaining it in a simple and clear example. Its very useful for beginners.

[anjumtadmod]

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 ?

[riteshtiwari]

Please make project video in lwc. Everyone looking project base learning.

[anubhavsingh]

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

[samankhan]
