state in react explained with example

Description:
Welcome to this video from tutorialsinhand.com. In this video we are going to discuss on state in react.

State in React
The state is a built in object in React, which is used to contain data that has been put in and which can be utilized and modified under different user interactions, system generated events or even in different phases of the component life cycle.
Previously, states were only available for use in the class components and function components solely depended on props and had no way to handle its own state data. But with the advent of React 16.8, hooks were introduced in React which benefitted by allowing developers to use state and separate the logic for maintenance of state and side effects from the main component in functional components, hence making them stateless which further increases code reusability. Besides this, they help the developers to "hook into" React state and lifecycle features from functional components.
