What are the key differences between React and Vue?

React is a JavaScript library focused on building user interfaces, while Vue is a progressive framework for building UIs. React uses a virtual DOM and is more flexible, whereas Vue offers a more opinionated structure and is easier to integrate into projects.

Which one is better for a beginner to learn?

Vue is often considered more beginner-friendly due to its simpler syntax and clear documentation. React, while powerful, has a steeper learning curve because of its ecosystem.

Can you explain the component lifecycle in both?

In React, components have lifecycle methods like componentDidMount and componentWillUnmount. Vue has a similar concept with lifecycle hooks such as created and mounted, but they are more straightforward to use.

What about performance? Is one faster than the other?

Both frameworks are optimized for performance, but React's virtual DOM can lead to faster updates in complex applications. Vue's reactivity system is also efficient, but performance can vary based on how you structure your app.
