nodejs is a modern javascript-oriented server framework typically used to provide various services and realtime applications, while node is an older framework for transmitting data packets over amateur radio.
js (Node) is an open source development platform for executing JavaScript code server-side. Node is useful for developing applications that require a persistent connection from the browser to the server and is often used for real-time applications such as chat, news feeds and web push notifications. Node.
A node is a basic unit of a data structure, such as a linked list or tree data structure. Nodes contain data and also may link to other nodes. Links between nodes are often implemented by pointers. It is a computer connected to the internet that participates in the peer to peer network.
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.
In Erlang I was able to immediately understand the notion of a 'node' - a self-contained Erlang VM. I could start a node on one machine with erl -name gandalf -setcookie abc, and another node on another machine (on the same LAN) with erl -name bilbo -setcookie abc. I could then spawn processes on gandalf which would communicate magically with other processes on bilbo. Now, since I also wanted to serve up a jazzy webpage with animated graphical results from my Erlang processes, I picked up some Javascript and learnt jQuery. Still a humble paduwan, but I sort of understand how Javascript fits into the scheme of things.
I recently came across node.js and an (evil) voice started whispering: 'This is it! Now you can do everything with Javascript! Forget Erlang and guards and periods, stick to a language that everyone uses'.
I've read the docs a bit, but I still don't understand what a node is in node.js. Do I have to run a http server and that becomes my node? What if I don't like http, or I don't care how gandalf talks to bilbo - that's what I like in Erlang. Maybe I nai:vely expect that node.js is erlang with Javascript sugar?
