Ok this is probably a little blunt and to the point, but what is the point/need for Node.js
I've noticed it mainly through CloudFoundry but just not too sure what its supposed to be doing. However I am guessing its probably something pretty big as why else would VMWare be supporting it.
Thanks in advance.

Closures are useful because they let you associate data (the lexical environment) with a function that operates on that data. This has obvious parallels to object-oriented programming, where objects allow you to associate data (the object's properties) with one or more methods.
In JavaScript, closures are the primary mechanism used to enable data privacy. When you use closures for data privacy, the enclosed variables are only in scope within the containing (outer) function. You can't get at the data from an outside scope except through the object's privileged methods.
Node. js is primarily used for non-blocking, event-driven servers, due to its single-threaded nature. It's used for traditional web sites and back-end API services, but was designed with real-time, push-based architectures in mind.
The short answer is “NO.” The long answer is, “NO, it's not dead, and it probably will never die.” Node. js is just as relevant to coding in 2021 and beyond, even if the hype around it has stabilized slightly.
It's an...

Node.js does IO right. It's asynchronous and non-blocking and the beauty of using js is that it does not have a standard blocking IO.
It's fast (v8 is a beast), it scales well, It's got a vibrant community and it's popular.
There are lots of wonderful libraries that run on node like now and socket.io.
It excels at real time communication and highly concurrent websites.
It also has the added bonus of less code duplication. You can write the same MVC code on the client as the server and easily support non-js users.
