Node is far from the first or only implementation of the reactor pattern in programming languages. There are many other, frequently more mature implementations which exist in most languages.

> Reasons why JavaScript was picked for Node.js: 1) It already dealt with events due to its usage in browsers and 2) a fast existing JIT runtime, V8.

Well, no, the original creator of Node just wanted non-blocking IO (which the frameworks he was using did not support), and (I'm editorializing a bit here) in the grand engineering tradition of re-inventing the wheel, he decided to use Javascript with v8 to create a whole new platform, instead of using an existing platform.
