Question
Select an appropriate statement which is true regarding props: (Select any two).Can be modified based on user interactionCannot be changed in child componentCan be accessed only in parent componentCan be assigned to state of the component
Solution
-
Cannot be changed in child component: This statement is true. Props are read-only in child components. They are passed down from the parent component and cannot be modified by the child component.
-
Can be assigned to state of the component: This statement is also true. Props can be assigned to the state of a component. However, changes to the state do not affect the original props.
