"Evented I/O for V8 JavaScript."

V8 is a very fast JavaScript engine
open sourced by Google.

Now, it is being used as embedded into other systems.

So, JavaScript becomes a universal language,
not only scripting for web browsers.

An irony of this is that Google itself is trying hard
to hide JavaScript from developers, for example by using
translation from Java to JavaScript in GWT, Google Web Toolkit.

But, this also makes sense: JavaScript is different
in various web browsers, and it is a huge waste of time
to take care about this manually each time.

On the other side, when a dialect of language is fixed,
JavaScript becomes a powerful language
due to its functional programing features,
as well as its dynamic and scripting nature...
