Should a child component have states or should it rely on props

Question

can you please help me to know Should a child component have states, or should it rely on props?

Answer 1

Whether a child component should have its own state or rely on props depends on the component's responsibility and how it interacts with other components.

State in Child Components:

A child component should have its own state if it is responsible for managing its own local behavior that is independent of the parent component. For example, if the child component manages input forms, toggles, or animations that do not need to be shared with the parent, then it makes sense to use local state within the child.

Props in Child Components:

A child component should rely on props if its data and behavior are controlled by the parent component. The child component should be stateless and simply render content or handle UI logic based on the props it receives. This is particularly useful when the child component needs to display or manipulate data that is shared across multiple parts of the application.
