Display digital clock using React

by vsasikalabe Updated: Jan 24, 2023

Create a Digital Clock using React using class Date. When Digital Clock is mounted a Digital Clock should update the state variable time with current Time. This Digital Clock should update the time variable regularly at an interval of 1 sec.The componentDidMount() method allows us to execute the React code when the component is already placed in the DOM (Document Object Model). This method is called during the Mounting phase of the React Life-cycle i.e after the component is rendered.The componentWillUnmount() method allows us to execute the React code when the component gets destroyed or unmounted from the DOM (Document Object Model). This method is called during the Unmounting phase of the React Life-cycle i.e before the component gets unmounted.The clearInterval() method clears a timer set with the setInterval() method.
