How does Node.js handle concurrency and scalability?

Additionally, Node.js has a built-in cluster module that allows us to easily scale your application across multiple CPU cores.

Is Node.js suitable for developing large-scale enterprise applications?

Yes, Node.js can be used to develop large-scale enterprise applications, particularly those that require high scalability and real-time data processing. Node.js has been used by large companies such as Walmart, Netflix, and PayPal to develop high-performance, scalable applications.
