sir when we can do CRUD operation on button click event or onload event or onchange event then why we need getter and setter?
we can also implement validations in same oncliick function

[@sfdcstop]

Good question Ronak. The answer is simple:- Reusability. Sometimes it happens that you're using the same object at multiple places/forms and it can be updated from anywhere. So, getters and setters are the best way to ensure that the validations will be applied no matter where the object is being used.

Hi,
why are you using lightning card inside div tag... both are used to group related information right. Then what is the need of using two tags.

[@sfdcstop]

Hi, that's only added to provide a specific defined width to my card which is mentioned in the div.

How can we pass value from parent Aura component to child (get set) variable

[@sfdcstop]

Hi srinivas, you can simply create an @api annotated variable in lwc and pass it's value from parent aura component.

If we want to display a property like {Person.FirstName} using getter, what would be the name of the get mehod ?

[@sfdcstop]

get firstName()

[@sfdcstop]

You can also use get personFirstName() if there are more firstName fields

[@bansigosaliya8703]

@@sfdcstop doesn't seem to be working with either :(

[@sfdcstop]

name of getter won't return you any data, you need to return the data yourself depending upon what record you're having

[@bansigosaliya8703]

@@sfdcstop Specific getter will be called depending on the value attribute yeah? But variable like Person.FirstName can have dot notation, method names can't. So seems getter can't be used without changing variable name.
