What are the differences in component lifecycle between Angular and React?

Angular and React have different approaches to component lifecycles. Angular uses a series of lifecycle hooks like ngOnInit, ngOnChanges, and ngOnDestroy, while React uses methods like componentDidMount, componentDidUpdate, and componentWillUnmount.

Can you explain what ngOnInit does in Angular?

ngOnInit is a lifecycle hook in Angular that is called after the component's data-bound properties have been initialized. It's a good place to perform any additional initialization tasks.

How does componentDidMount work in React?

componentDidMount is a lifecycle method in React that is invoked immediately after a component is mounted. It's commonly used for fetching data or setting up subscriptions.

Are there any performance implications between the two?

Yes, performance can vary based on how each framework handles updates and re-renders. React's virtual DOM can lead to more efficient updates, while Angular's change detection strategy can sometimes be less performant if not managed properly.
