Node.js is similar in purpose to Twisted for Python, Perl Object Environment for Perl, and EventMachine for Ruby. Unlike most JavaScript, it is not executed in a web browser, but it is rather related to server-side JavaScript. Node.js implements some CommonJS specifications[1]. Node.js includes a REPL environment for interactive testing.
