Yes. Node.js runs JavaScript on a single thread, but uses a thread pool for blocking work and is designed for high concurrency through non-blocking I/O. It scales very well for I/O-bound work like APIs and real-time apps.
No. Node.js is a runtime, an environment that runs JavaScript. Express is a framework. Mongoose is a library. Node.js is the runtime that runs them all.
