Thanks sir for this series

[@priyankaravichandran851]

Much usefull , great explanation 👌👍

[@ankitsethia6534]

In child.component.ts, property name is _loggedIn and in app.component.html, you used loggedIn (without underscore) , then how come your code executed fine?
Anyways many thanks for the detailed concepts provided.

[@markodanielgekic1984]

because the setter is called 'loggedIn ' and it is the input parameter

[@vishtrinity]

why use getter and setter when we can actually access and manipulate variable using @Input() ?

[@chandansharma6849]

By using setter we can receive data from parent to child and can run some execute some code in setter function, every time child receive data.

[@lehlohonololefatle6300]

Can the child component update data in the parent using this method?

[@nivedithaprabhakaran7158]

Why to use _ before loggedin . Is that a decorator or convention?

[@exploringtheworld08]

because the setter is called 'loggedIn ' and it is the input parameter

[@AGUNGKAYA]

just convention

[@vikramravichandran9607]

How to pass multiple variable to child component?

[@catalogonelwin7240]

You can pass an object instead of just a single value :)

[@sidharthvijayakumar3521]

why is it ===??

[@issambaccouch6358]

=== faster than == in the background

[@LegendKopper]

@@issambaccouch6358 This is true but the performance difference is irrelevant. === is strict equality, which also compares the datatypes.
