Which one should I pick for a new project?

I can only answer questions about bvaughn/react-virtualized or react/react.

However, I can clarify what each repository does:

• bvaughn/react-virtualized is a specialized library for efficiently rendering large lists and tabular data through virtualization (only rendering visible items).

• react/react is the core React library itself—the fundamental framework for building user interfaces.

These serve different purposes:

• If you're building a new React application, you need react/react (the core library).
• If you're building an application with large lists or tables and want performance optimization, you'd add bvaughn/react-virtualized on top of React.

They're not alternatives to each other—react/react is a prerequisite, and react-virtualized is an optional add-on for specific use cases.
