Can I update a component's props in React.js?

Question

After starting to work with React.js, it seems like props are intended to be static (passed in from the parent component), while state changes base

Answer 1

PROPS

A React component should use props to store information that can be changed, but can only be changed by a different component.

STATE

A React component should use state to store information that the component itself can change.

A good example is already provided by Valéry.
