Q: What is the difference between state and props?

1 Answer

The state is a data structure that starts with a default value when a

Component mounts. It may be mutated across time, mostly as a result of

user events.

Props (short for properties) are a Component’s configuration. Props are how

components talk to each other. They are received from above component

and immutable as far as the Component receiving them is concerned. A

Component cannot change its props, but it is responsible for putting together

the props of its child Components. Props do not have to just be data —

callback functions may be passed in as props.
