One of the method is using properties( a.k.a Props ) Lets see how to handle data using props: React handles default props by merging the passed props object and the default props object.

They are one of the early things you will learn in React after initially grasping React's JSX syntax.

where the real data is. This is because Now we initialize React's state from props; and whenever someone types something into the input field, this state gets updated to reflect the new value in the component (see controlled component in React) without caring about new props , if the component re-renders, at all, because the initial state is only initialized once.

It is easy to pass props to state in react hooks, but do you know how to sync props changes to state changes after initialization. It is also easy, lets see that in this article. Now we initialize React's state from props; and whenever someone types something into the input field, this state gets updated to reflect the new value in the component (see controlled component in React) without caring about new props, if the component re-renders, at all, because the initial state is only initialized once. React has another special built-in object called state, which allows components to create and manage their own data. So unlike props, components cannot pass data with state, but they can create and manage it internally.
