NodeJS

Nodejs

As an asynchronous event driven JavaScript runtime, Node is designed to build scalable network applications. Thread-based networking is relatively inefficient and very difficult to use.

Furthermore, users of Node are free from worries of dead-locking the process, since there are no locks. Almost no function in Node directly performs I/O, so the process never blocks. Because nothing blocks, scalable systems are very reasonable to develop in Node. Node is similar in design to, and influenced by, systems like Ruby's Event Machine or Python's Twisted. Node takes the event model a bit further. It presents an event loop as a runtime construct instead of as a library.
