Tell us about the stages of the React component lifecycle.

The React component lifecycle includes several key stages, which can be divided into three phases: mounting, updating, and unmounting.

1. Mounting — when the component is created and added to the DOM:

   • constructor — initializing state and binding methods.
   • static getDerivedStateFromProps — synchronizing state with props (rarely used).
   • render — rendering the markup.
   • componentDidMount — called after the component is inserted into the DOM; useful for API calls or subscribing to events.

2. Updating — when the component receives new props or state changes:

   • static getDerivedStateFromProps — updating state based on new props.
   • shouldComponentUpdate — optimizing rendering by returning true/false.
   • render — re-rendering.
   • getSnapshotBeforeUpdate — capturing information before the DOM updates.
   • componentDidUpdate — called after updates; can react to changes.

3. Unmounting — when the component is removed from the DOM:

   • componentWillUnmount — cleaning up resources, unsubscribing from events.

In functional components with hooks, the lifecycle is managed through useEffect, which can mimic the behavior of mounting, updating, and unmounting methods depending on the dependencies passed.
