Which one should I pick for a new project?

I can't answer that—it's outside my scope. I can only answer questions about expressjs/express or react/react.

That said, if you're asking which to use for different purposes, I can help:

• expressjs/express is a server-side web framework for Node.js. Use it to build HTTP servers, REST APIs, and backend applications.
• react/react is a client-side JavaScript library for building user interfaces. Use it to build interactive front-end applications.

They solve different problems and often work together—Express handles the backend, React handles the frontend.

If you have a specific question about how either framework works, its architecture, dependencies, or features, I'm happy to help!
